4. a. Design a Combinational circuit with three inputs, A, B, and C, and four outputs, U, V, W and X. Construct the circuit with two inputs NOR gate only.When the decimal value of input is 4, 5, 6, or 7 the binary output is one less than the input (input -1). When the decimal value of input is 0, 1, 2, or 3, the output is two greater than (input +2) the input. 

b. A majority circuit is a combinational circuit whose output is equal to 1 if the input variables have more no. of 1’s than 0’s. The output is 0 otherwise. Design Using Boolean laws, three input Majority circuit with P, Q, R as input output Function T and its complement circuit, Prove 𝑻 = (𝑻 ′ ) ′ .
