Question

Using MATLAB, duplicate to the two graphs shown in the figure below Requirements 1. Show the MATLAB code used to plot both functions 5cos (nt-ng) (V) 5 e-"X cos (2nft-2nx/A) (V) a. y b- Use the frequency, wavelength and attenuation shown in the figure below when plotting graph (b) 2. 3. 4. Place labels for the x and y axis showing appropriate units Extend the x-axis to 10 cm and use a sampling rate of 0.1 mm Submit the final paper in the form of a word document including the MATLAB code and the graph generated; upload to Canvas before the assignment deadline Module 1.2 Traveling Waves Learn how the shape of a traveling wave is related to its frequency and wavelength, and to the attenuation constant of the medium. Module 1.2 Traveling Waves Input for blue wave Instructions Frequencyf- 0.80236 H The travefrg wave shown in red is given by y 5cos(nt-nx) volts. Thus. ts frequency is o.5 Hz. its wavelength is zem, and its reference phase anje OO·0, with t-O denned as the me the animation is started. For comparison.you can generate and display in blue a waveform gven by Attenuation -0253 by specitýng ts attrioutes in the input Panel. 10.803 [Hz] 2 [cm] @p=0° 2.874 [cm] Mots] 5 6 Icmi

Answer 1

x=0:1e-2:10;
t=0:0.1:5;
for n=1:length(t)
y=5.*cos(pi.*t(n)-pi.*x);
plot(x,y);
title(['t= ' num2str(t(n))]);
xlabel('x(cm)');
ylabel('y');
pause(0.1);
clear figure
end
hold off
