Q1. Write the truth table for a 1-to-2 decoder. Draw a circuit which implements a 1-to-2 decoder using AND gates, OR gates and NOT gates only.
Q2. Given a supply of 2-to-4 decoders, show how to get a 4-to-16 decoder circuit. Assume each of the 2-to-4 decoders has an ENABLE input (ENABLE = 1 enables the decoder), but you need not include an enable capability on the 4-to-16 decoder circuit.
