Briefly describe how we can use a decoder optimally to implement a given Boolean function? Illustrate your answer with the help of an example. 6. Draw truth tables for the following:
(a) an 8-to-1 multiplexer with active LOW inputs and an active LOW ENABLE input;
(b) a four-line to 16-line decoder with active HIGH inputs and active LOW outputs and an active LOW ENABLE input;
(c) an eight-line to three-line priority encoder with active LOW inputs and outputs and an active LOW ENABLE input.
