Question

DESIGN SECTION You are going to design which has 4 inputs wi L V. and 4 outputs A, B.Cand D. The features of the circuit are; a combinational eircuit Inputs (w, x, y, z) Binary Code Outputs (A, B, C, DGray Code The circuit encodes Input Bit Sequence (Binary Code) to Gray Code. You are going to; a) Fill the truth table according to your design. b) Find the simplified AND-OR expressions for all 4 outputs (Sum of Product) by using 4-variable K-map. e) Draw the logic diagram of the simplified functions of all 4 outputs by using just 2- inputs-Logic gates.

Answer 2

Design a combinational circuit with 4 inputs (A, B, C, D) and 4 outputs (w, x, y, z). 1. When the input variables have more 0's than 1's the output 3 greater than input. 2. When the input variables have more 1's than 0's the output 3 less than input. 3. When the input variables have 0's equal to 1's the output is the same as input a) simplify and implement using AND and OR gates b) implement using a decoder and external gates. *
