Butterworth Filter: What is it? (Design & Applications)

The Butterworth filter is a type of signal processing filter designed to have a frequency response that is as flat as possible in the passband. It is also referred to as a maximally flat magnitude filter.

At the time, filter design required a considerable amount of designer experience due to limitations of the See more A transfer function of a third-order low-pass Butterworth filter design shown in the figure on the right looks like this: A simple example of a Butterworth filter is the third-order low-pass design shown in the figure on the … See more There are several different filter topologies available to implement a linear analogue filter. The most often used topology for a passive realisation is the Cauer topology, and the most often used topology for an active realisation is the Sallen–Key topology. See more The frequency response of the Butterworth filter is maximally flat (i.e. has no ripples) in the passband and rolls off towards zero in the stopband. When viewed on a logarithmic See more Like all filters, the typical prototype is the low-pass filter, which can be modified into a high-pass filter, or placed in series with others to form band-pass and band-stop filters, and higher … See more Properties of the Butterworth filter are: • Monotonic amplitude response in both passband and stopband • Quick roll-off around the cutoff frequency, which improves with … See more WebThe Butterworth filter is normalized for a −3 dB response at ω 0 = 1.
