Abstract |
|
In audio signal processing parallel filters are highly efficient to reduce noise in the signal and also power consumption. In this proposed design parallel filter is designed in the following method: firstly the target response is smoothened, then warped IIR filters are designed to the smoothed target response which was divided into bands, and finally the united pole set is used to design the parallel filter. Warped FIR is not preferable because it is an all zero filter so poles cannot be selected to reduce the noise in audio signals, and also effective results could be achieved only at higher orders. Due to this computational cost and complexity increases. So by using warped IIR filter the problems of warped FIR can be reduced. |
