Web16.2.1 Butterworth Low-Pass FIlters The Butterworth low-pass filter provides maximum passband flatness. Therefore, a But-terworth low-pass is often used as anti-aliasing filter in data converter applications where precise signal levels are required across the entire passband. Figure 16 – 5 plots the gain response of different orders of ... WebExample 1: A 1-kHz, 5-pole, 0.5-dB Chebyshev Low-Pass Filter. As an example, we will examine a 1-kHz, 5-pole, 0.5-dB Chebyshev low-pass filter. A few reasons for this specific choice: 1) Unlike the Butterworth case, the center frequencies of the individual sections are all different. This allows a graph that spreads out the traces
