Abstract
A method and device for detecting on an electric fence system a communication signal from a total signal including noise and also electrical interference from electrical energizer pulses supplied to the fence. A signal detector detects, directly or indirectly, the level of noise or electrical interference in the total signal on the system, at least one of a filter associated with the signal detector and the amplitude of the total signal received is adjusted until the threshold of the filter blocks sufficient electric noise so that a sufficient part of the total signal received after filtering is the communication signal, and the adjustment of the filter threshold is not dependent on the communication signal alone. The validity of the communication signal is checked and the electrical energizer pulses are transmitted on the fence system in coordination with reception of the communication signals to reduce the interference.
