truth table of 4 bitparallel subtractor

Design a circuit that either Adds or subtracts 3 from a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit number M. When K=0, M=N+3. When K=1, M=N-3. Assume that the inputs for which M>11112 or M˂00002 will never occur and K is the most significant variable in the truth table. Implement your design with one 4-bit Binary Adder, one Quad 2-1 Multiplexer and NOT gates as required. a. Implement the function M3 with Two-Level NAND-NAND form. Assume that double-rail inputs are available from the source. b. Implement the functions M2 with a 5:32 decoder constructed from four 3:8 decoders with enable input E, one 2:4 decoder, and an external OR gate with a large fan-in. c. Realize the function M1 with a single 8-to-1 MUX. Take K, N3, N2 as selection inputs. d. Realize the function M0 with four three-state buffers, one 2:4 decoder, and other logic gates as required. Take N1, N0 as decoder inputs
