BUTTERWORTH FILTER DESIGN
Objective The main purpose of this laboratory exercise is to learn the procedures for designing Butterworth filters In addition the theory behind these |
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 formula for the 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.
On top of that, there now are zeros for .
