    摘要: There is described a system for controlling the movement of an animal relative to a controlled area delineated by a wire loop antenna. The controlled area may be inclusive or exclusionary. A frequency modulated signal is transmitted by the FM transmitter connected to the loop. An FM receiver attached to the animal detects the transmitted signal and provides an alarm signal to the animal. The loop antenna is untuned. Low radio frequencies are used and the carrier frequency deviation is large to reduce the systems susceptability to noise. The modulating frequency is limited, also to reduce susceptibility to noise. Integrated circuits are especially designed to permit operation with very low power.
