Part 1 Circuit #1 : An OR gate Using just three NAND gates, create an OR function with two inputs and one output. Write the truth table first for the circuit. Hint: You might need to tie some inputs together, similar to the input in the example circuit. Circuit #2: A NOR gate Using just four NAND gates, create a NOR (not OR) function with two inputs and one output. Write the truth table first for the circuit. Hint: You might need to tie some inputs together, similar to the input in the example circuit
