How to Design 10 kHz filter (Using Butterworth filter design
This application note demonstrates how to build 10 kHz filter applying Butterworth filter design Using the same techniques even better filter can be obtained
Why Butterworth filter is better?
The Butterworth filter is the best compromise between attenuation and phase response. It has no ripple in the passband or the stopband, and because of this it is sometimes called a maximally flat filter.
What is the use of Butterworth filter in image processing?
True Butterworth filter This causes the transition from the passband to the stopband to be more gradual at any given order. This can be seen in the following images which appear a bit sharper in the lowpass case than their squared Butterworth counterparts above.
What is a Butterworth filter used for?
The Butterworth filter is a type of signal processing filter designed to have as flat frequency response as possible (no ripples) in the pass-band and zero roll off response in the stop-band. Butterworth filters are one of the most commonly used digital filters in motion analysis and in audio circuits.
In the field of Image Processing, Butterworth Highpass Filter (BHPF) is used for image sharpening in the frequency domain. Image Sharpening is a technique to enhance the fine details and highlight the edges in a digital image. It removes low-frequency components from an image and preserves high-frequency components.
Butterworth filters are used in control systems because they do not have peaking. The requirement to eliminate all peaking from a filter is conservative. Allowing some peaking may be beneficial because it allows equivalent attenuation with less phase lag in the lower frequencies; this was demonstrated in Table 9.1.
