Hi,
I must to design a Butterworth filter using Matlab.
Parameter:
- butterworth Highpass filter
- cut-off frequency 0.2-05 Hz
- attenuation 70\80dB
In a Workspace I have two vectors (a time vector and a data vector)
Example:
time=[0,1,2,3];
data=[32,54,65,23];
signal=plot(time, data);
Data vector contains the signal values for each instant of time (sampling frequency: 120.83 Hz).
What can I do to make the filter for this signal?
I have tried using: “butter” and using: “Toolboxes – Filter Design”.
Thank you at all.
