The development of a transistorized relay amplifier of superior performance to vacuum-tube type of amplifiers commonly used is described. The circuit was designed from an analytic approach utilizing matrices amenable to digital computer solution for the performance of a large amount of computations. The digital computer permitted a thorough survey of parameter studies and illustrates a powerful design method extendible to circuits of greater complexity. Performance tests of the transistorized relay amplifier with the analog computer showed it to be superior to the vacuum-tube type in lower noise level, a smaller inactive zone, and much faster time response.
