Abstract
Oscillators phase locked to transitions in the envelope of a bandwidth-limited complex waveform are used, for example, in detecting MPSK signals. The magnitude of the envelope is approximated by linearly combining the real and imaginary components of the complex waveform, or by selecting the larger of the two components, or by using both these techniques in combination.
