Consider the following combinational circuit: where (A,B,C,D) are binary inputs, (T₁​ ,T₂​ ,T₃​,T₄​ ) are intermediate logic; and Y is the final logic output.
(a) Derive the Boolean expressions of Tᵢ 's and Y.
(b) List the truth table of Tᵢ​ 's and Y. Use K-map to simplify the circuit. Draw that circuit.
