Input Generators for Digital Sound Synthesis
Godfrey Winham, Kenneth Steiglitz · The Journal of the Acoustical Society of America · 1970
A fast method is described for generating a periodic discrete-time signal with harmonics of equal amplitude and a fundamental frequency which is not necessarily an integral fraction of the sampling frequency (as with ordinary pulse generators). Such a signal can be used as input to digital filters for the synthesis of speech and music.
