5 Questions
What is a multiplexer?
A combinational circuit with more than one input line, one output line, and more than one selection line.
What is the purpose of an ENABLE or STROBE input in multiplexer ICs?
It needs to be active for the multiplexer to be able to perform its intended function.
How does a multiplexer select binary information?
It selects binary information present on any one of the input lines, depending upon the logic status of the selection inputs, and routes it to the output line.
How is the number of maximum possible input lines related to the number of selection lines in a multiplexer?
If there are n selection lines, then the number of maximum possible input lines is 2n.
What does a 2n-to-1 multiplexer refer to?
A multiplexer with 2n maximum possible input lines and 1 output line.
