Abstract :
A simple method for generating a class of time-sequency-amplitude plots called Walsh spectrograms is presented. A Fortran computer program which enables one to generate such spectrograms readily is provided. Illustrative examples related to generating spectro-grams associated with pulse-code modulation and speech data are included.
