About this document
Digital Filter Design Overview by Carlton Lobo is a document available to read on EtoBox.
This document discusses digital filter design. It begins by presenting ideal lowpass, highpass, bandpass and bandstop filters and explains why ideal filters cannot exist in practice due to being non-causal. The Paley-Wiener theorem establishes conditions for the existence of causal filters approximating a desired frequency response. Practical filter specifications are then described in terms of passband ripple, stopband attenuation and transition widths. The goal of rational approximation is discussed along
