Q1. Minimize the given Boolean Expression by using the four variable k-map with the Don’t Care conditions and draw the circuit.

F (A, B, C, D) = Σ m (1, 5, 6, 10, 11, 12)+d(2,4).

Implement the circuit before and after the minimization.

Q2. Design a combinational circuit with four inputs, w, x , y , and z , and four outputs, A, B , C and D. When the binary input is 0, 1, 2, or 3, the binary output is two greater than the input. When the binary input is 4, 5, 6, or 7, the binary output is one less than the input. Solve with four inputs and outputs.
