Transition bands much smaller than what can be achieved from analog fil-ters; an example would be a lowpass filter with a bandwidth of 5000 Hz and a passband ripple of 0.5 dB, and 100 dB attenuation ... Inspectrum analyzers and synthesizers, vocoders (voice recorders), and simi-lar devices, extremely low tolerances on the magnitude and phase responsesover adjacent passbands are required, and digital...
