Marks compare the results after filtering the noisy signal
Question 01 (30 marks)
Refer to Physionet.org (https://www.physionet.org/) to get download recorded physiological signals. Physiobank ATM would allow to download various types of recorded physiological signals such as EEG, ECG… etc.
Data format – standard
Signal format - .mat (use toolbox) (5 marks)
(5 marks)
Plot the 50Hz noise added ECG signal in time domain. (5 marks)
Using Matlab coding design a FIR filter to remove 50/60Hz hum noise of the above downloaded modified ECG signal. (8 marks )
Apply the above designed filter to the ECG noisy signal to remove the 50Hz hum noise.
(6 marks)
