4. a. Design a Combinational circuit with three inputs, (A, B, and C) and four outputs, (U, V, W, and X) with the 2- i/p NOR gate only for the following logic. When the decimal value of the 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 circuits with P, Q, and R as input, output Function T and its complement, Prove.
