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)

5. Plot the 50Hz noise added ECG signal in time domain. (5 marks)

1. Using Matlab coding design a FIR filter to remove 50/60Hz hum noise of the above downloaded modified ECG signal. (8 marks )

2. Apply the above designed filter to the ECG noisy signal to remove the 50Hz hum noise.

(6 marks)

Question 03 – (30 marks)

(d) Apply the designed filter to the above noisy signal and filter the noise. (5 marks)

(e) Plot the filtered signal in time domain. (5 marks)
