MATLAB Practice:

Using version R2021b

MATLAB code which tweaks the following code.

close all
x = 0: pi/100: 2 * pi;
wave1 = sin (x * 3);
wave2 = sin (x * 7) + cos (x * 8);

plot (x, wave1, 'b-', x, wave2, 'r:');
legend ('wave 1', 'wave 2');
title ('Some Example Data Waveforms');
xlabel ('Angle');
ylabel ('Amplitude');

a. Use subplot(3,1,x)
b. Draw “wave1” with stem function in subplot(3,1,1) with xlabel, ylabel and legend
c. Draw “wave2” with stem function in subplot(3,1,2) with xlabel, ylabel and legend
d. Draw “wave1” and “wave2” with stem function in subplot(3,1,3) with xlabel, ylabel, legend and title.

x = 0: pi/100: 2 * pi;
wave1= sin (x * 3);
wave2 = sin (x * 7) + cos (x * 8);
plot (x, wavel, 'b-', x, wave2, 'r:');
legend ('wave 1', 'wave 2');
title ('Some Example Data Waveforms');
xlabel ('Angle');
ylabel ('Amplitude');
