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. It was first described in 1930 by the British engineer and physicist Stephen Butterworth in his paper entitled "On the Theory of Filter Amplifiers". WebExpert Answer.

Design and Implementation of Butterworth Filter

WebOct 15, 2024 · Butterworth filter: The transfer function of the Butterworth high pass filter (BHPF) of order n and with cutoff frequency locus at a distance Do from the origin is defined by the relation. Figure 5.2 shows a perspective plot and cross section of the BHPF function. Note that when D (u, v) = Do, H (u, v) is down to ½ of its maximum value. WebThe Fig. 2.79 shows the first order high pass Butterworth filter. It can be observed that as compared to first order low pass filter, the positions of R and C are changed in the high pass circuit shown in Fig. 2.79. The frequency at which the gain is 0.707 times the gain of filter in pass band is called as low cut off frequency and denoted as f L.
