Multiplexers:
It is a combinational circuit that has many data inputs and single output depending on control or select inputs. For N input lines, log n (base2) selection lines, or we can say that for 2n input lines, n selection lines are required. Multiplexers are also known as “Data n selector, parallel to serial convertor, many to one circuit, universal logic circuit”.
- Number of input lines = n
- Number of select lines = m
- The number of n selected input lines is equal to 2m.
- n = 2m. The Correct Answer is n = 2m.
