In recent studies, a non-parametric speech waveform representation (rep.) based on zeros of the z-transform (ZZT) has been proposed. The ZZT rep. has successfully been applied in separating mixed phase signals, e.g. pitch-synchronously windowed speech, into min/max phase by using the unit circle as discriminant. As the ZZT rep. is obtained by factorization of the z-transform, relations to the complex...
The relationship between z-transform and Fourier transform of a discrete series is presented. The Fourier transform of a discrete series whose z-transform has poles on the unit circle can be derived using these results.<<ETX>>
