ABSTRACT:
An improved method for generating various wave functions for use in musical tone generation in FM synthesis so as to substantially reduce computational and storage requirements. The waveform desired to be used is mathematically modeled using piecewise linear approximation. A reduced number of coefficients of the piecewise linear approximation, representing the angles and offsets of the linear segments, are stored in memory.
