I need help with the following

2. A NOR gate is a gate that performs the OR operation on two inputs, then negates the output. It is equivalent to chaining an OR gate into a NOT gate, so (p NOR q) : NOT(p OR q). Here is a picture of a NOR gate: (a) Draw a truth table for the NOR gate. (b) Draw a Circuit that computes the biconditional implication 4) operation on two inputs using only NOR gates. (Hints: You may want to gure out how to do AND, OR, and NOT rst. The same input can go into a NOR gate twice if necessary.)
