How to design a Butterworth High Pass filter?
High-Pass Butterworth filters
We can just multiply the numerator and the denominator by to get a more familiar form: | H n , h p ( j ω ) | = ω n 1 + ω 2 n As you can see, the poles will be the same as for the low-pass version.
What is Butterworth High Pass filter?
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.
What is Butterworth filter design?
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.
