Question

To get an output Y = 1 from the circuit shown below, the input must be

Options

A.
B.
C.
D.

Solution

          
The Boolean expression of the given circuit is
     Y = (A + B).C
The truth table of the giiven signals as shown in the table
     
From the table truth we conclude that output Y = 1, for the inputs A = 1, B = 0, C = 0Hence option (c) is correct.
