SIGNAL SYNTHESIS Estimates the time-domain signal from a given time-frequency distribution. The signal synthesis routine is limited to the following time-frequency distributions: (i) Short-Time Fourier Transform (STFT) (ii) Spectrogram (iii) Wigner-Ville Distribution PARAMETERS: TIME-FREQUENCY MATRIX Input matrix containing the time-frequency distribution. SIGNAL Output synthesised (complex) signal from given time-frequency distribution. WINDOW LENGTH Length of the smoothing window used in the given distribution (or in the case of of the WVD the lag window length). ANALYSIS TYPE Specifies which type of signal synthesis will be applied to the given TFD matrix. The following analysis types are valid: (i) STFT: (a) Inverse Discrete Fourier Transform method. (b) Overlap-Add method. (c) Modified Short-Time Fourier Transform method. (ii) Spectrogram: Modified Spectrogram method (iii) Wigner Ville Distribution: Wigner Ville Distribution method. The original signal can be specified to correct the phase of the synthesised signal. See Also: wvd, spec
