Plotting of transfer functions

Sir, I drew the graph below, but I could not do the above. I'll be glad if you take a look.

Below graph:

A = 60;

B = 160;

%Setting up the figure%

X_Position = 100;

Y_Position = 100;

Width = 1200;

Height = 300;

figure('Position', [X_Position Y_Position Width Height])

%Case a)%

r = (0:256);

r(r > A & r < B) = 0;

s = r;

subplot(1,3,1); plot(s,'LineWidth',2);

title("Option a)")

xlabel("r"); ylabel("T(r)");

What else is there to do? You made the plot, so what else do you want? The "above" just gives you instructions for making those waveforms, which you've done, so what's the remaining problem?

Sir, i want to graph of option b. I can't do graph of option b.

I don't see any such labels "Option a" or "Option b" on the image. You plotted the waveform in the lower half of the image and titled it "Option a)" - not sure why. But it looks like you accepted Ameer's answer so I guess you're all set.

Try this

A = 60;
B = 160;
%Setting up the figure%
X_Position = 100;
Y_Position = 100;
Width = 1200;
Height = 300;
figure('Position', [X_Position Y_Position Width Height])
%Case a)%
r = (0:256);
r(r > A & r < B) = 0;
s = r;
subplot(1,3,1); plot(s,'LineWidth',2);
title("Option a)")
xlabel("r"); ylabel("T(r)");

r = (0:256);
s = zeros(size(r));
s(r > A & r < B) = 250;
subplot(1,3,2); plot(s,'LineWidth',2);
title("Option b)")
xlabel("r"); ylabel("T(r)");

Sir, option b is not correct. It will start at y[i]=25 & 255

[Ameer Hamza]

The plot was not clearly visible. Change the last part of the code to

r = (0:256);
s = 25*ones(size(r));
s(r > A & r < B) = 255;
subplot(1,3,2); plot(s,'LineWidth',2);
title("Option b)")
xlabel("r"); ylabel("T(r)");

Sir, thank you for answer.
