A SERVO-CONTROLLED NULLING SYSTEM FOR REDUCING RADIO FREQUENCY INTERFERENCE

Abstract

Naval shipboard communication systems have always been afflicted with the problem of radio frequency interference between receivers and transmitters located on the same ship. A servo controlled nulling system is analyzed to determine its feasibility as a method of reducing radio frequency interference caused by nearby transmitters. Limitations on the practical form of the system are studied. Experimentation includes the measurement of null depths for low-level interfering signals.
