ABSTRACT:
A loss-of-signal (LOS) condition is detected by sampling input data for a predetermined time period, comparing a magnitude of the sampled input data to a threshold signal strength level, and asserting a LOS indication if the number of samples that have signal strength less than the threshold signal strength level is less than a predetermined value.
