We consider small depth boolean circuits with basis {AND, OR, NOT}. We obtain lower bounds for the parity function using a relatively simple method. We prove that for any depth 3 circuit with top fan-in t, computing the n-variable parity function must have at least t2n-1/t wires. Similarly, we obtain a lower bound for computing the depth 4 circuits.
