Circuit is or gate if dosing of switch is an input. Circuit is and gate if opening of switch is an input. Provides phase inversion of input. If both switches are open, both transistors are nonconducting. When either switch is dosed, output is negative, or not or, because of phase inversion, and circuit is therefore nor gate.- Transistor Manual, Seventh Edition, General Electric Co., 1964, p 176.
