(Multiplexers versus Demultiplexers) Multiplexers and demul-tiplexers are related closely, but there are important differences.
(a) Briefly, define and differentiate the following terms: decoder, demultiplexer, and multiplexer. Mention the number of inputs, outputs, enable, and select bits, if any.
(b) Using AND and OR gates, design a circuit to gate a single data input to one of four output lines, determined by the binary-encoded index on the two control lines. Which of the above parts did you design?
