Shipboard Interference Simulator. Analog Computer-Like Device Developed at NEL Reproduces Frequencies Derived from Intermodulation between Combined Transmitter Fundamentals

Abstract

A shipboard interference simulator was designed which accurately reproduces the potential frequencies of interference derived from the intermodulation between any combination of simultaneous transmitter fundamental frequencies up to a total of 10. The relationship of interference-signal magnitudes is in reasonable agreement with similar signals actually measured aboard ship. The simulator proved its worth as an aid in demonstrations of intermodulation interference before Naval personnel concerned with shipboard communications problems. The simulator represents an analog computer with which detailed knowledge of intermodulation pehnomena can be increased. It is especially valuable when more than the classic two fundamental signals are on together.
