A switching circuit that produces one in a set of input bits as an output based on the control value of control bits is termed as
Choose the correct answer:
A.
Full Adder
B.
Inverter
C.
Multiplexer
(Correct Answer)
D.
Converter
Correct Answer:
Multiplexer
Explanation
A Multiplexer (often abbreviated as MUX) is a combinational logic circuit designed to switch one of several input lines to a single common output line.
Functionality: It acts like a "data selector." It has 2n input lines and n selection (control) lines.
Control Mechanism: The digital code applied to the control bits determines which specific input bit is routed to the output.
Example: In a 4-to-1 multiplexer, there are 4 inputs and 2 control bits. If the control bits are set to 00, the first input is produced at the output; if set to 01, the second input is produced, and so on.
