Abstract
A new partially differential cepstrum is defined, which can be regarded as a new type of differential cepstrum. It saves half computational complexity compared with the previously defined differential cepstrum since only one dimension of partial derivative is considered. Nevertheless, this suffices for avoiding phase-unwrapping in complex-cepstrum calculation. As an application of complex cepstrum, we also introduce a windowing technique to construct the minimum-phase sequence from a mixed-phase one.
