![]() ![]() ![]() The operation of the decoder will get clarified by the truth table. As an example, consider a 3:8 decoder, the three inputs are decoded into eight outputs, each representing one of the minterms of the three input variables. Let’s start with the theory behind it.Ī decoder is a combinational circuit that converts binary information from n input lines to a maximum of 2^n unique output lines. ![]() Many a times, it happens that we don’t have a larger decoder, so we normally combine small decoders to design a bigger one. So today’s topic is designing a 5:32 decoder using 4 3:8 decoders and a 2:4 decoder. Connecting the A input to the selection line will convert a 2:1 multiplexer into an AND gate. How to design an AND gate using 2:1 multiplexer ?Got the answer? If not, then here is the answer. ![]()
