Abstract
A signal generator includes a pseudo-random bit generator that feeds bits three screening gates and three interconnected counters to simulate the electronic interference noise source attributed to three 400 hertz motors. The electronic interference effect includes fluctuations of frequencies to represent the slight variations in motor-generator speeds attributed to the 400 hertz motors so that a more realistic evaluation can be made on nearby communications and navigation equipments.
