Yes, we could do that to replicate the blue curve, but then we would not be able to easily change the cutoff frequencies. What we liked about the Butterworth filter was that we can easily change the cutoff frequencies in the filter design. However, it is not that close to the original one. We...
Hi,
It is not for school. I currently work in a resarch group and we are developping a wearable device which will analyse human body movements. We need to filter the collected data (like acceleration) to remove the undesirable frequencies and to reduce noise.
Hi,
I need to replicate a bandpass filter of which I only have the A et B coefficients (numerator and denominator of the Z-transform function). It is the blue curve in this picture.
The goal is to approach this curve with my own filter, so I could eventually change the cutoff frequencies if...
