Abstract :
The peak amplitude of a waveform for a particular spectrum depends on the phases of its harmonic components. Previous work on peak amplitude reduction has only considered individual spectra. This paper compares various phase selection methods, and shows that genetic algorithm optimization gives results 10%-25% lower than the other methods
