Each of these functions applies a fourth order parallel IIR filter to one signal packet and updates the filter state.
The fourth order parallel IIR filter is represented by the following figure:
Each of the functions takes the following arguments:
Destination signal array.
Source signal array.
Internal filter structure.
Number of signal samples.
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
