    • A.

      10,5 B

    • B.

      10,5 KB

    • C.

      10,5 MB

    Correct Answer
    C. 10,5 MB
    Explanation
    The given answer is 10.5 MB. This can be calculated by multiplying the duration of the audio CD (1 minute) by the sampling rate (44.1 kHz) by the sample size (16 bits) by the number of channels (2).

    1 minute * 44.1 kHz * 16 bits * 2 channels = 1,411,200 bits

    Converting bits to bytes:

    1,411,200 bits / 8 = 176,400 bytes

    Converting bytes to megabytes:

    176,400 bytes / 1,048,576 = 0.168 MB

    Rounding it to one decimal place, the file size for storing such a recording would be approximately 10.5 MB.

    • B.

      Intra-frame

    • C.

      Key-frame

    Correct Answer
    A. Inter-frame
    Explanation
    Inter-frame compression refers to a video compression technique that reduces the file size by analyzing the differences between consecutive frames. It only stores the changes that occur between frames, rather than storing each frame individually. This allows for efficient compression and reduces the amount of data that needs to be transmitted or stored. In contrast, intra-frame compression compresses each frame independently, while key-frame compression stores complete frames at certain intervals. Therefore, inter-frame compression is the correct term for this type of compression.

    Osnovna ideja Huffmanovog kodiranja je da se:

    • A.

      Karakteri koji se češće javljaju kodiraju kraćim sekvencama

    • B.

      Karakteri koji se češće javljaju kodiraju dužim sekvencama

    • C.

      Karakteri koji se češće javljaju kodiraju istim sekvencama

    Correct Answer
    A. Karakteri koji se češće javljaju kodiraju kraćim sekvencama
    Explanation
    Huffmanovo kodiranje je tehnika kompresije podataka koja se temelji na principu da se češće javljajući karakteri kodiraju kraćim sekvencama, dok se rjeđe javljajući karakteri kodiraju dužim sekvencama. Ovaj pristup omogućuje efikasnije kodiranje i manju veličinu kodiranog podatka, jer se često korišteni karakteri predstavljaju sa manje bitova.

    Postupak zamene izmerene (semplirane) vrednosti analognog signala oznakom intervala vrednosti kome pripada naziva se:

    • A.

      Sempliranje

    • B.

      Kvantizacija

    • C.

      Kodiranje

    Correct Answer
    B. Kvantizacija
    Explanation
    The process of converting the measured (sampled) values of an analog signal into a set of discrete values is called quantization. In this process, the continuous range of values is divided into a finite number of levels or intervals, and each sampled value is assigned to the closest level. This allows for the representation of the analog signal using a limited number of bits, reducing the required storage or transmission capacity. Kvantizacija is the Serbian term for quantization.

    Aditivni model boja se prirodno primenjuje kada se boje grade dodavanjem komponenti svetlosti (RGB) kod:

    • A.

      Monitora i projektora

    • B.

      Printera

    • C.

      štampanja

    Correct Answer
    A. Monitora i projektora
    Explanation
    The additive color model is commonly used when creating colors on monitors and projectors. This model involves adding different components of light (red, green, and blue - RGB) together to create a wide range of colors. By combining these primary colors of light, monitors and projectors can produce a full spectrum of colors. This is different from the subtractive color model used in printing, where colors are created by subtracting certain wavelengths of light. Therefore, the correct answer is monitora i projektora.

    Dithering je smanjenje opsega boja na:

    • A.

      128

    • B.

      256

    • C.

      512

    Correct Answer
    B. 256
    Explanation
    Dithering is a technique used to reduce the color range in an image. In this case, the correct answer is 256 because dithering reduces the color range to 256 different colors. This means that instead of having a full range of colors, the image will only have 256 distinct colors to represent the original image. This reduction in color range helps to reduce file size and improve image compression without significantly affecting the visual quality of the image.

      Dithering

    • B.

      Kerning

    • C.

      Leading

    Correct Answer
    A. Dithering
    Explanation
    Dithering is the correct answer because it refers to the process of reducing the color range to 256. Dithering is a technique used in digital imaging to create the illusion of more colors by using patterns of different colors or intensities. It is commonly used when converting images with a higher color depth to a lower color depth, such as from a true color image (24-bit) to an indexed color image (8-bit). This technique helps to minimize color banding and create smoother transitions between colors. Kerning and leading, on the other hand, are typographic terms related to adjusting the spacing between characters and lines of text, respectively.
