Filter Design Assignment
In the enclosed data set you will find the measurements. Your task will be to filter out everything except the frequency bandwidth given below using a low-pass filter. The attached samples are sampled with frequency of 100Hz.
The parameters:
Cutoff - 20Hz
Ripple in the pass-band 0.8dB
Transition band - 2.6Hz
Attenuation in the stop-band larger than 28 dB
A) Include the Matlab code used to design the filter
B) Plot the magnitude and angle of the filter transfer function
C) Find the inverse filter and calculate the mean-square error between reconstructed and the original signal
