 Decoders are usually constructed with a control input called the Enable

Decoders are usually constructed with a control input called the Enable (EN) When EN is 0, all decoder outputs are 0: when EN is 1, the Decoder functions normally. The Enable input is also useful in allowing smaller Decoders to be combined to form larger ones. Sketch the gate-level implementation of a 2 times 4 Decoder with Enable input and complete its truth table: Show how to connect two 2 times 4 Decoders (with Enables) to form a 3 times 8 Decoder
