SignalUtils.CplxCepstrumInv Method

void CplxCepstrumInv(TVec Src, TVec Dst, Double PhaseLag, Int32 TargetLength)

Compute the inverse complex cepstrum.

#	Name	Type	Description
1	Src	TVec	source TVec
2	Dst	TVec	source TVec
3	PhaseLag	Double	scalar
4	TargetLength	Int32

Result: stored in self (calling object)

Remarks:

Compute inverse complex cepstrum of Src and place the result in Dst. Phase lag is the value returned by CplxCepstrum. TargetLength is the length of the original (not zero padded) signal passed to the CplxCepstrum routine.
