What is a decoder?

• • A. A circuit that converts a binary code into a set of outputs.

• • B. A circuit that combines several input signals into a single output signal.

• • C. A circuit that divides a single input signal into several output signals.

  • .

• • D. None of the above

What is active-high?

• .

• • A. A signal that is considered high or active or on, when it is in a logic 0 level or in logic low state.

• • B. A signal that is considered high or active or on, when it is in a logic 1 level or in logic high state.

• • C. A signal that is considered low or inactive or off, when it is in a logic 0 level or in logic low state.

• • D. A signal that is considered low or inactive or off, when it is in a logic 1 level or in logic high state

What is a priority encoder?

• • A. A circuit that converts a binary code into a set of outputs.

• • B. A circuit that combines several input signals into a single output signal.

• • C. A circuit that divides a single input signal into several output signals.

• • D. A circuit that generates an output code based on the highest priority input.

What is the function of the select lines in a priority encoder?

• • A. To select the input signal that will be forwarded to the output line.

  • the priority of the input signals.

• • B. To divide the input signal into several output signals.

• • C. To combine several input signals into a single output signal.

• • D. To determine the priority of the input signals.

What is the difference between a priority encoder and a decoder?

• • A. A priority encoder generates an output code based on the highest priority input, while a decoder converts a binary code into a set of outputs.

• • B. A priority encoder converts a binary code into a set of outputs, while a decoder generates an output code based on the highest priority input.

  • .

• • C. There is no difference between a priority encoder and a decoder.

• • D. None of the above
