Signal detection scheme for data communication links |
摘要 |
The present invention is a signal detect (SD)/loss-of-signal (LOS) circuit that is able to discern between received Signal and Noise in Digital Amplitude Modulated transmission systems. A window detector, having a low and high voltage limit, receives an input signal. A low pass filter having an output connects to the window detector. A differential comparator compares the output of the low pass filter at a negative input and a threshold voltage signal to generate an output signal indicative of the average power of the input signal.
