Maximally flat response
WebThe key feature of the Butterworth filter when compared to other forms of filters is that it has a nominally flat response within its pass-band and an adequate roll-off. As a result, the … WebThus graph is horizontal or flat, hence approximation is called maximally flat response. Consider amplitude function given by, In pass band of filter, f (ω 2) should be very small i.e. very less than 1. Then we can neglect f (ω 2) and the amplitude function can be written as, In stop band, f (ω 2) should be very high i.e. much greater than 1.
