SWEEP PILOT TECHNIQUE FOR A CONTROL SYSTEM THAT REDUCES DISTORTION PRODUCED BY ELECTRICAL CIRCUITS

摘要

A control system comprising an electrical circuit that produces distortion where the electrical circuit has a frequency band of operation. A pilot modulated carrier signal is generated and is cause to traverse across the frequency band of operation of the electrical circuit. Information obtained from the traversing pilot modulated carrier signal when it is determined that there is no interference between any signal appli ed to or generated by the electrical circuit. The information is used by the control system to substantially cancel the distortion.
