    Do koje mere se neki skup podataka moze komprimovati?(Shannon)

    • A.

      Entropija izvora H

    • B.

      Kapacitet kanala C

    Correct Answer
    A. Entropija izvora H
    Explanation
    The correct answer is "Entropija izvora H." Entropija izvora meri količinu informacija koja se može komprimovati u skupu podataka. Veća entropija znači da je skup podataka manje kompresibilan, dok manja entropija ukazuje na veću mogućnost kompresije. Stoga, do koje mere se neki skup podataka može komprimovati zavisi od entropije izvora.

      Kapacitet kanala C

    Correct Answer
    B. Kapacitet kanala C
    Explanation
    The correct answer is "Kapacitet kanala C" (Channel capacity C). Channel capacity refers to the maximum rate at which information can be reliably transmitted through a communication channel. It is determined by the channel's bandwidth and signal-to-noise ratio. The higher the channel capacity, the faster the communication speed. In this context, "krajnja brzina komuniciranja" (maximum communication speed) is synonymous with channel capacity.

    Correct Answer(s)
    A. Meru do koje se neki skup podataka moze komprimovati
    C. Prosecnu kolicinu informacija
    Explanation
    The correct answer is "Meru do koje se neki skup podataka moze komprimovati, Prosecnu kolicinu informacija." The explanation for this answer is that entropy of a source H defines the measure to which a set of data can be compressed and the average amount of information. Entropy represents the amount of uncertainty or randomness in a source, and by measuring it, we can determine the maximum compression that can be achieved on a given dataset. Additionally, entropy also represents the average amount of information contained in each symbol or data point from the source.

      Nije moguce dizajnirati komunikacionu semu bez greske

    • B.

      Moguce je dizajnirati komunikacionu semu koja je asimptotski bez greske prenosa

    Correct Answer
    B. Moguce je dizajnirati komunikacionu semu koja je asimptotski bez greske prenosa
    Explanation
    If the entropy of the source is less than the channel capacity, it means that the source has less uncertainty or randomness compared to the capacity of the channel to transmit information. In this case, it is possible to design a communication scheme that can asymptotically transmit data without errors. This means that with enough time and resources, the communication scheme can achieve error-free transmission.

    Rate this question:

  • 37. 

    Ako je verovatnoca poruke veca:

    • A.

      Kolicina informacije je manja

    • B.

      Kolicina informacije je veca

    Correct Answer
    A. Kolicina informacije je manja
    Explanation
    When the probability of a message is higher, it means that the message is more likely to occur. In information theory, the amount of information in an event is inversely proportional to its probability. Therefore, if the probability of a message is higher, the amount of information it carries is lower. Hence, the correct answer is that the amount of information is smaller when the probability of a message is higher.

    Rate this question:

  • 38. 

    Poruka A ima verovatnocu ?, a poruka B ?

    • A.

      Kolicina informacije je veca u poruci A

    • B.

      Kolicina informacije je veca u poruci B

    • C.

      Kolicine informacije su jednake u obe poruke

    Correct Answer
    A. Kolicina informacije je veca u poruci A
    Explanation
    The answer is that the quantity of information is greater in message A. This is because the question states that message A has a probability of ?, while message B has a probability of ?. Since the probabilities are not specified, we can assume that the probability of message A is higher than the probability of message B. In general, the higher the probability of an event, the less surprising or informative it is. Therefore, if the probability of message A is higher, it means that message A contains less surprising or expected information compared to message B, making the quantity of information greater in message A.

    The statement is saying that the amount of information should decrease as the probability of the message increases. This is true because if a message is very probable, it carries less information since it is expected and not surprising. On the other hand, if a message is unlikely, it carries more information because it is unexpected and surprising. Therefore, the statement is correct.

    Mera za kolicinu informacije treba biti takva da monotono raste sa porastom verovatnoce poruke

    • A.

      Tvrdnja je tacna

    • B.

      Tvrdnja nije tacna

    Correct Answer
    B. Tvrdnja nije tacna
    Explanation
    The statement suggests that the amount of information should increase monotonically with the probability of the message. However, this is not true. In information theory, the amount of information is inversely proportional to the probability of an event. The more probable an event is, the less information it carries. Therefore, the statement is incorrect.

    Za optimalno kodovanje poruke:

    • A.

      Bitno je opisati kolicinu informacije u porukama

    • B.

      Nije bitno ako je kolicina informacije ispod kapaciteta kanala C

    • C.

      Nije bitno ako je mali broj poruka

    Correct Answer
    A. Bitno je opisati kolicinu informacije u porukama
    Explanation
    In order to achieve optimal coding of a message, it is important to describe the quantity of information in the messages. This means that the coding should accurately represent the information content of the message. It is not relevant whether the quantity of information is below the capacity of the channel or if there are only a few messages. The focus should be on accurately describing the information in the messages.

    Ako neko posalje dve poruke:

    • A.

      Ukupna kolicina informacije je jednaka zbiru pojedinacne kolicine informacije dve poruke

    • B.

      Ukupna kolicina informacije je jednaka entropiji H

    • C.

      Ukupna kolicina informacije jednaka je proizvodu pojedinacne kolicine informacije dve poruke

    Correct Answer
    A. Ukupna kolicina informacije je jednaka zbiru pojedinacne kolicine informacije dve poruke
    Explanation
    The correct answer is "Ukupna kolicina informacije je jednaka zbiru pojedinacne kolicine informacije dve poruke." This statement is based on the principle that the total amount of information is equal to the sum of the individual amounts of information of two messages. In other words, when two messages are sent, the total amount of information transmitted is the sum of the amount of information in each message.

      Logaritam

    • B.

      Algoritam

    • C.

      Limes

    Correct Answer
    A. Logaritam
    Explanation
    The correct answer is "Logaritam" because the logarithm is a mathematical function that measures the amount of information in a given context. It is commonly used in information theory to quantify the amount of information contained in a message or data set. The logarithm helps to compress and represent information in a more concise and efficient manner. Additionally, the properties of logarithms, such as the ability to combine and simplify expressions, make it a useful tool for measuring and analyzing information.

    • D.

      Nijedan od izraza

    Correct Answer
    B. I(x)= -log2 px
    Explanation
    The expression I(x) = -log2 px is the correct formula for calculating the amount of information. It represents the negative logarithm of the probability of event x occurring, multiplied by the logarithm base 2. This formula is derived from Shannon's information theory, where the amount of information is inversely proportional to the probability of an event occurring.

    • C.

      Nijedan od odgovora

    Correct Answer
    B. Kolicina informacije izrazava se u bit
    Explanation
    When using a logarithm with base two, the quantity of information is expressed in bits. This is because the binary system, which is based on two digits (0 and 1), is commonly used to represent and store information in computers. In the binary system, each bit represents a single unit of information, making it the appropriate unit of measurement when using a logarithm with base two.

    Ako izvor generise 4 poruke verovatnoce ?, kolicina informacije po jednoj poruci iznosi:

    • A.

      4 bit-a

    • B.

      2 bit-a

    • C.

      8 bit-a

    • D.

      1 bit

    Correct Answer
    B. 2 bit-a
    Explanation
    The correct answer is 2 bit-a. This is because the amount of information in a message is determined by the number of possible outcomes, which is equal to the logarithm base 2 of the number of outcomes. In this case, there are 4 possible outcomes, so the amount of information per message is log2(4) = 2 bit-a.

    • B.

      8 bit-a

    • C.

      16 bit-a

    • D.

      2 bit-a

    Correct Answer
    B. 8 bit-a
    Explanation
    If a source generates 4 messages with equal probabilities, the total amount of information can be calculated by multiplying the number of messages by the number of bits needed to represent each message. In this case, since there are 4 messages and each message requires 2 bits to represent (log2(4) = 2), the total amount of information is 8 bits.

    Entropija izvora predstavlja:

    • A.

      Prosecnu kolicinu informaciije

    • B.

      Maksimalnu kolicinu informacije

    Correct Answer
    A. Prosecnu kolicinu informaciije
    Explanation
    Entropija izvora predstavlja prosečnu količinu informacije koju izvor generiše. Ova mera se koristi za kvantifikaciju neizvesnosti ili nesigurnosti u informacijama koje izvor proizvodi. Prosečna količina informacije se računa kao suma verovatnoća svih mogućih događaja pomnožena sa negativnim logaritmom te verovatnoće. Što je veća entropija, to je veća nesigurnost ili neizvesnost u informacijama koje izvor generiše.

    Ako imamo binarni izvor informacije, onda entropija binarnog izvora zavisi od:

    • A.

      Verovatnoce poruka

    • B.

      Brzine izvora (b/s)

    • C.

      Redudanse

    Correct Answer
    A. Verovatnoce poruka
    Explanation
    The entropy of a binary source depends on the probabilities of the messages. The more probable a message is, the lower its entropy will be. This is because the entropy measures the average amount of information needed to represent a message from the source, and if a message is highly probable, it requires less information to represent it. Therefore, the probabilities of the messages directly affect the entropy of the binary source.
