Modulation and Periodic Properties of Temporal Envelope,ime-reversed speech sample is used as a good example demonstrating the phase effect on intelligibility. The envelopes also provide estimates of the fundamental period of a periodic sequence. This chapter introduces the period estimation of a periodic scheme when the fundamental of a signal is missing.

Sampling Theorem and Discrete Fourier Transform, theorem is given in terms of the DFT and the partial sum of the Fourier series expansion for a continuous periodic function. In understanding the DFT schemes, it is informative seeing what happens if the sampling theorem is violated. Modifications of sequences through interpolation and decimation are displayed using numerical examples.

Discrete Sequences and Their Fourier Transform,n, .-transform, Fourier transform, analytical representation of sequences, magnitude and phase, and poles and zeros of complex functions. The topics covered in this chapter are very elementary or introductory, but provide the basis on which all other issues dealt with in this book are constructed.
