Abstract
Near threshold, an envelope detector suffers losses in both amplitude and phase. The classic threshold analysis computes only the amplitude loss. Here the phase loss is computed and shown to be larger than the amplitude loss. This places additional limitations on an envelope detector when used with coherent signals.
