FIR_EC

Computes FIR filter results.

Syntax

IppStatus ippsFIR_EC_16s(const Ipp16s* pSrcSpchRef, const Ipp16s* pSrcSpch, Ipp16s* pDstSpch, int len, Ipp16s* pSrcTaps, Int tapsLen);

IppStatus ippsFIR_EC_32f(const Ipp32f* pSrcSpchRef, const Ipp32f* pSrcSpch, Ipp32f* pDstSpch, int len, Ipp32f* pSrcTaps, Int tapsLen);

pSrcSpchRef	Pointer to the source original receive-out signal (R_out ) of length (tapsLen + len) .
pSrcSpch	Pointer to the send-in signal (S _in) with echo path.
pDstSpch	Pointer to the destination send-out signal (S_out ) which is echo-free.
len	Length of source and destination signals.
pSrcTaps	Vector of FIR filter taps .
tapsLen	Number of taps in the FIR filter.

The functions ippsFIR_EC are declared in the ippsc.h file.

These function perform finite impulse response (FIR) filtering.

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
