quantization effects in designing digital filters

Abstract: 114th of time-domain and frequency-domain characteristics. Conventional audio filter designs tend to , is a function of the transition band. Whilst this expression does not represent an optimal filter , distortion in the upper regions of the audio band is much less audible [20]. For a typical minimum phase , the phase distortion over the audio band it was decided to implement a series of filters and allow , prototype filter with a 240dB stop band. 2. minimum phase with tailored response 3. minimum
