Analyzing networks containing diodes by analog computation

Larrowe's direct simulation method of analyzing electrical networks with an analog computer is extended to include ideal diodes. The technique is somewhat artificial; each diode is replaced by a small inductance that passes cur rent in one direction. The limit as the value of the induct ance approaches zero is simply a high-gain limited ampli fier that introduces feedback to preserve all current and voltage equations at all times. The stability of the method is briefly discussed and an example is given to show its effectiveness.
