1. Implement the NOT, AND, and OR gates by using NAND gate only 2. Implement the NOT, AND, and OR gates by using NOR gate only 3. Give some applications for XOR, and NOR logic circuits.

Draw a transistor schematic for the one-bit ripple-carry adder. The schematic should not however, include the sum. We concentrate only on the logic that produces Cout. Also use only NAND and/or NOR gates.
