Abstract
A new method of spectrum analysis, harmonic transform, is proposed to provide an impulse-train spectrum for signals that are comprised of time-varying harmonics. The essential concept of the transform and some of its properties are discussed. Based on the new transform, a short time harmonic transform is developed for time-frequency analysis. Simulation examples dealing with voiced speech show that the harmonic transform can provide a better frequency representation for signals that contain time-varying harmonics.
