Implement Notch Filter to remove 50 Hz on ECG signal

Load & plot ECG signal in time domain and implement Notch Filter to remove 50 Hz with Q fator 1

%% TASK UNDER PROGRAM 2:
% PROCEED PROGRAM 2 ONLY AFTER COMPLETION OF PROGRAM 1
% (2-a) Use Subplot to show both signals together(original signal on the
% top(blue colour) and bottom is filtered Signal after notch implementation(red colour).
% (2-b) Use Subplot to show both signals together(original signal on the
% left(blue colour) and right is filtered Signal after notch implementation(red colour).
% (2-c) Plot both signals one over other with Original signal in red and.
% Filtered outupt in green and display only 0 to 201 samples or time frame
% of 0 to 0.804
% (2/1) Learn what does all the comand do in help section and add as
% comment.
% (2/2) Vary the Q factor from 1 to 35 in interval of 5 and check if any
% changes observed.
