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.PARAMETERSEach 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 VALUESEach of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Committed | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+SEE ALSOmlib_SignalIIR_Biquad_S16_S16_Sat(3MLIB), mlib_SignalIIRFree_Biquad_S16_S16(3MLIB), mlib_SignalIIRFree_P4_S16_S16(3MLIB), mlib_SignalI- IRInit_Biquad_S16_S16(3MLIB), mlib_SignalIIRInit_P4_S16_S16(3MLIB), attributes(5) SunOS 5.11 2 Mar 2007 mlib_SignalIIR_P4_S16_S16_Sat(3MLIB)
