Generation of a composite mitigation signal with a desired spectral energy distrubution

A method of generating a composite mitigation signal is presented. The composite mitigation signal includes an odd integer (N) of transitions between a first amplitude and a second amplitude of the composite mitigation signal. Successive sets of the transition bursts are separated by a desired phase delay or time delay, or such separations are defined by a base signal having a frequency equal to a fundamental frequency of the composite mitigation signal. The composite signal generators that generate the composite mitigation signal are also presented.
