摘要：The present invention provides an improved apparatus and method fordetecting a reverse carrier signal. The present invention utilizes a peak

detector/envelope filter for determining the peak level of the reverse analog waveform.The peak level is compared to a threshold level during a predetermined time period todetermine the presence of a valid reverse carrier signal. Once determined, an enablesignal is provided to an electronics device that allows further transmission of the reversesignals.
