engineering recuitment GATE EE 2023-24 Test Series Digital Electronics Combinational Circuits Multiplexer
An 8 : 1 multiplexer has inputs A, B and C connected to the selection inputs S2, S1 and S0 respectively. The data input P0, P1, ….. Pr (associated with selection S2 S1 S0 = 000, 001, ….. 111 respectively) are as follows. P1 = P2 = P7 = 0; P3 = P5 = 1; P0 = P4 = D; and P6 = D̅.
