摘要：
A control system comprises an electrical circuit (108) that produces distortion where the electrical circuit has a frequency band of operation. A pilot modulated carrier signal (produced by 171,188) 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 applied to or generated by the electrical circuit is used by the control system to substantially cancel the distortion.
