Remember: All In Class Lab Assignments are due before you leave the lab. 1. A logic circuit accepts a natural binary number DCBA in the range 0 to 15 (the least-significant bit is bit A). The output is the square of the input; for example, if DCBA = 0101, = 5, the output is 00011001, = 25Draw a truth table for this problem, and implement the circuits for each output: a) Using the K-Map to obtain a simplified expression, b) Construct a circuit to implement the function using NAND gates only. c) Construct a circuit to implement the function using NOR gates only.
