Abstract: Design methods of IIR filters have been proposed with design examples to present the effectiveness of the design methods. However, we point out that the evaluation of the design methods is ...

Until recently, audio systems have largely been analog. Now the trend is moving rapidly to digital implementations. While the literature contains most of the information needed to design and implement ...

An infinite impulse response (IIR) filter library for Linux, Mac OSX and Windows which implements Butterworth, RBJ, Chebychev filters and can easily import coefficients generated by Python (scipy).
