Performs band pass filtering.
IppStatus ippsBandPassFilter_RTA_32f_I(Ipp32f* pSrcDst, int len, Ipp32f* pMem);
pSrcDst |
Pointer to the source and destination vector [len]. |
len |
Number of elements in the source and destination vectors. |
pMem |
Pointer to the memory allocated for the band pass filter [len+2]. |
The function ippsBandPassFilter_RTA is declared in the ippsc.h file.
This function performs frequency enhancement around half of the bandwidth by cascading lowpass and highpass first order filters with the unit gain at stop band, and maximum gain ~ 3.56 db at about 8 kHz with 16kHz sampling rate.
ippStsNoErr |
Indicates no error. |
IppStsNullPtrErr |
Indicates an error when one of the specified pointers is NULL. |
IppStsSizeErr |
Indicates an error when len is less than or equal to 0. |
