The 10-kHz second-order Butterworth filter (Q = 0.707) shown in Figure 1 is used here as an example. Butterworth filters have a maximally flat pass-band response, which is a desirable trait for most analog signal paths. A higher-order Butterworth filter further flat-tens the pass-band response and provides higher attenua-
