Rangkaian Decoder, Encoder, Flip-Flop
- B.
Rangkaian Encoder, Decoder, Demultiplexer
- C.
Rangkaian Multiplexer, Decoder, Encoder
- D.
Rangkaian Multiplexer, Adder, Comparator
Correct Answer
A. Rangkaian Decoder, Encoder, Flip-FlopExplanation
The correct answer is "Rangkaian Decoder, Encoder, Flip-Flop". The reason is that a flip-flop is a sequential circuit, not a combinational circuit. Combinational circuits produce output based solely on the current input, whereas sequential circuits also take into account the previous state. Therefore, a flip-flop does not belong in a list of combinational circuits. The other options all consist of combinational circuits only.Rate this question:

Rangkaian yang mempunyai dua buah output yang selalu berada dalam kondisi berlawanan (Q) dan (Q') adalah
- A.
Rangkaian Demultiplexer
- B.
Rangkaian Flip-Flop
- C.
Rangkaian Inverter
- D.
Rangkaian Decoder
Correct Answer
B. Rangkaian Flip-FlopExplanation
A flip-flop is a circuit that has two outputs, Q and Q', which are always in opposite states. When the input signal triggers a change, the output Q will switch to its opposite state while Q' will switch to the same state as Q. This characteristic of flip-flops makes them suitable for storing and synchronizing data in digital systems. In contrast, a demultiplexer is a circuit that has multiple outputs but they are not necessarily in opposite states. An inverter is a circuit that has only one output that is the opposite of its input. A decoder is a circuit that has multiple outputs but they are not necessarily in opposite states.Rate this question:

- A.
Tetap
- B.
Toggle
- C.
Set
- D.
Terlarang
Correct Answer
D. TerlarangExplanation
If the output of the Flip-Flop circuit (Q) = (Q') = 1, it means that both the output and its complement are high. In a Flip-Flop, this condition is not allowed because it violates the fundamental behavior of a Flip-Flop. In a Flip-Flop, the output and its complement should always be opposite to each other. Therefore, if both Q and Q' are high, it is considered an invalid state and is referred to as "Terlarang" or forbidden.Rate this question:

- D.
AB'C', ABC, A'BC, ABC'
Correct Answer
A. A'BC, AB'C, ABC', ABCExplanation
The correct answer is A'BC, AB'C, ABC', ABC. This is because the condition states that the output will be 1 if the majority of the inputs are 1. In the given table, for each row, we can determine the output by counting the number of 1's in the inputs. If there are more 1's than 0's, the output will be 1. Therefore, in the first row, there are no 1's, so the output is 0. In the second row, there is one 1, so the output is 0. In the third row, there is one 1, so the output is 0. In the fourth row, there are two 1's, so the output is 1. This pattern continues for the remaining rows, resulting in the answer A'BC, AB'C, ABC', ABC.Rate this question:

10101011(2) = ________(8)
Correct Answer
253Explanation
The given question asks for the octal representation of the binary number 10101011. To convert a binary number to octal, we group the binary digits into sets of three from right to left. In this case, we have 101 010 11. Each group is then converted to its corresponding octal digit. The octal representation of 101 is 5, 010 is 2, and 11 is 3. Therefore, the octal representation of 10101011 is 523. However, the given answer is 253, which is incorrect.Rate this question:

- C.
Rangkaian Flip-Flop
- D.
Rangkaian Kombinasional
Correct Answer
D. Rangkaian KombinasionalExplanation
A "Rangkaian Kombinasional" is a logic circuit whose output depends solely on the combination of its input logic levels at any given moment. It does not have any memory elements, such as flip-flops, that can store information. Therefore, the output of a combinational circuit is determined only by the current input values and does not rely on any past inputs or outputs.Rate this question:

Rangkaian Inverter
- C.
Rangkaian Flip-Flop
- D.
Rangkaian Kombinasional
Correct Answer
A. Rangkaian SekuensialExplanation
A sequential circuit is a circuit whose output is influenced by both the input conditions and the previous output state. It operates based on the sequence of events or the order of time. In contrast, a combinational circuit only depends on the current input conditions and does not have any memory of previous outputs. An inverter is a basic logic gate that simply changes the input signal to its opposite state. A flip-flop is a type of sequential circuit that stores a single bit of data and can change its output based on a clock signal. Therefore, the correct answer is "Rangkaian Sekuensial" or sequential circuit.Rate this question:
