Which of the following is a basic combinational circuit?
Analysis & Theory
A multiplexer is a combinational circuit that selects one input from many and forwards it to the output.
A Half Adder adds:
D
One binary and one decimal digit
Analysis & Theory
A half adder adds two single-bit binary numbers and produces a sum and a carry.
What is the output of a Full Adder?
Analysis & Theory
A full adder adds three inputs (A, B, Cin) and outputs Sum and Carry.
Which circuit selects one of many inputs and directs it to a single output line?
Analysis & Theory
A multiplexer (MUX) selects one input from multiple inputs based on select lines.
Which combinational circuit converts binary input into one active output line?
Analysis & Theory
A decoder activates one of several output lines based on binary input values.
What is the function of an Encoder?
C
Converts multiple input lines into a binary code
Analysis & Theory
An encoder converts multiple active inputs into a binary output code.
Which component distributes data from one input to multiple outputs?
Analysis & Theory
A demultiplexer (DEMUX) sends input data to one of the multiple output lines based on select lines.
How many output lines does a 3-to-8 decoder have?
Analysis & Theory
A 3-to-8 decoder has 2³ = 8 output lines.
Which circuit can be used to implement any logic function?
Analysis & Theory
A multiplexer can be used to implement any combinational logic circuit.
A full subtractor requires how many inputs?
Analysis & Theory
A full subtractor requires three inputs: Minuend, Subtrahend, and Borrow In.
