Many of the useful properties of pre-envelopes of real waveforms are shown to hold when the notion of pre-envelope is applied to random processes which are not wide-sense stationary. In particular, if x(t) represents a real random process which is not wide-sense and d?(t) is its Hilbert transform, t
