A combinational circuit is one in which the output depends on the ____

1.	A combinational circuit is one in which the output depends on the ____________(a) Input combination at the time(b) Input combination and the previous output(c) Input combination at that time and the previous input combination(d) Present output and the previous outputThis question was addressed to me in a national level competition.My doubt is from Multiplexers (Data Selectors) topic in section Combinational Circuits of Digital Circuits
Answer» The correct choice is (a) INPUT combination at the time To elaborate: A combinational circuit is one in which the OUTPUT DEPENDS on the input combination at the time, whereas, a sequential circuit is one in which the output depends on present input as WELL past outputs.
