       #include <mlib.h>

       mlib_status mlib_SignalIIR_P4_S16_S16_Sat(mlib_s16 *dst,
	    const mlib_s16 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalIIR_P4_S16S_S16S_Sat(mlib_s16 *dst,
	    const mlib_s16 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalIIR_P4_F32_F32(mlib_f32 *dst,
	    const mlib_f32 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalIIR_P4_F32S_F32S(mlib_f32 *dst,

DESCRIPTION

       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.

PARAMETERS

       Each of the functions takes the following arguments:

       dst	 Destination signal array.

       src	 Source signal array.

       filter	 Internal filter structure.

       n	 Number of signal samples.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
