Computation of the One-Dimensional Unwrapped Phase
Zahi N. Karam,Alan V. Oppenheim +1 more
TL;DR: Two composite algorithms are proposed that build upon the existing ones based on recent advances in polynomial factoring for computing the unwrapped phase of the discrete-time Fourier transform of a one-dimensional finite-length signal.

The cepstrum: A guide to processing
TL;DR: The power, complex, and phase cepstra are shown to be easily related to one another, and the interpretation and processing of data in such areas as speech, seismology, and hydroacoustics is discussed.

Stability criterion for recursive filters
TL;DR: A new criterion is derived that relates the stability of two-dimensional recursive filters to the properties of its cepstrum, and provides a procedure for the decomposition of unstable recursive filters having nonzero, nonimaginary frequency response into stable recursive filters.

The computation of two-dimensional cepstra
TL;DR: Two methods of computing the complex cepstrum of a two-dimensional (2-D) signal are explored and the relationship among the nonzero regions of a signal, its inverse, and its cEPstrum is explored.
