May 24, 2014 · OVERVIEW: Combinational circuit is a circuit in which we combine the different gates in the circuit for example encoder, decoder, multiplexer and demultiplexer. Combinational circuit consists of logic gates whose outputs depend on the present inputs.
A combinational circuit consists of logic gates whose outputs, at any time, are determined by combining the values of the inputs. For n input variables, there are 2n binary input combinations. possible. • For each binary combination of the input variables, there is one possible output.
