Each of these functions applies a fourth order parallel IIR filter to one signal packet and updates the filter state.
Printed copy or docs.sun.com displays an equation that represents the fourth order parallel IIR filtering.
The fourth order parallel IIR filter is represented by the following figure:
Printed copy or docs.sun.com displays a figure that represents the fourth order parallel IIR filter.
Each of the functions takes the following arguments:
dst
src
filter
n
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
