A combinational circuit with four inputs (A, B, C, D) and one output (Z) is designed as follows using an 8:1 multiplexer. Inputs A, B,C are connected to the select lines S2. S1. Sg respectively. Multiplexer has the following values connected to the data inputs: lo, I4 = D; I,Is = 0; Iz,1, = 1; Iy,1, = D' For the circuit given above a) Fill the truth table. b) Using the Karnaugh map, simplify the output function as the sum of the products and write the simplest logic expression of the circuit realized above z = f (A,B,C, D).
