In the given 4-to-1 multiplexer, if c1 = 0 and c0 = 1 then the output M is ___________(a) X0(b) X1(c) X2(d) X3The question was posed to me by my school principal while I was bunking the class.My doubt is from Multiplexers (Data Selectors) in section Combinational Circuits of Digital Circuits

Answer»

The CORRECT answer is (B) X1

Easy explanation: The OUTPUT will be X1, because c1 = 0 and c0 = 1 results into 1 which further results as X1. And rest of the AND gates GIVES output as 0.
