Initializes the state memory of high-pass filter.
IppStatus ippsHighPassFilterInit_AMRWB_16s(Ipp16s* pFilterCoeffA, Ipp16s* pFilterCoeffB, int order, IppsHighPassFilterState_AMRWB_16s* pState);
order |
The order of high-pass filter; orders of 2 and 3 are currently supported. |
pFilterCoeffA |
Pointer to the vector of order size containing the IIR part of the filter coefficients . |
pFilterCoeffB |
Pointer to the vector of order size containing the FIR part of the filter coefficients. |
pState |
Pointer to the memory supplied for filtering. |
This function is declared in ippsc.h file. It sets the coefficients and initializes the state memory of the high-pass filter.
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when one of the specified pointers is NULL. |
ippStsRangeErr |
Indicates an error when order is not equal to either 2 or 3. |
