SIGNAL ANALYSIS AND SYNTHESIS USING SPECTROGRAM CONSTRUCTION AND INVERSION

Abstract: a method for generating an analog signal for signal analysis, which includes the steps of receiving analog spectrogram data that characterizes one or more bands, constructing an analog signal from the analog spectrogram data, discretely sampling the analog signal for a time period comprised of a sequence of equal time intervals to create a digital signal with values that characterize the analog signal for each of the time periods, constructing a digital spectrogram from the digital signal, wherein the digital spectrogram represents the rate of change of amplitude with respect to time and frequency; and computing an analog spectrogram from the digital spectrogram, wherein an analog spectrogram represents the one or more bands in units of time, frequency and amplitude for the time period.
