Diode Coincidence and Mixing Circuits in Digital Computers

Basic circuits utilizing germanium diodes in electrically pulsed systems are described. The circuits are of the following types: 1. Coincidence circuits-output signal occurs only when all the inputs receive signals simultaneously. 2. Mixing circuits-output signal occurs when any one of the inputs receives a signal. The analyses of transient response of the output signal and the input impedance are given.
