SOFTWARE IMPLEMENTATION OF DIGITAL FILTERS

How do you implement a digital filter?
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 Butterworth filter in digital image processing?
Butterworth filters are one of the most commonly used digital filters in motion analysis.
They are fast and simple to use.
Since they are frequency-based, the effect of filtering can be easily understood and predicted.What is the procedure to design a digital Butterworth filter?
The most straightforward way to implement a digital filter is by convolving the input signal with the digital filter's impulse response.
All possible linear filters can be made in this manner. (This should be obvious.
If it isn't, you probably don't have the background to understand this section on filter design.
