MATLAB: Plotting of transfer functions

Question

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)");

Answer 1

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)");
