Experiment 2 - Double Sideband Amplitude Modulation-Long Carrier (DYBGM-UT) and Interpretation

1a) Run the code below. Fill in the blanks in the code. Write the required titles with the "title" command. Comment the graphics.

1b) In the experiment, run a separate code for the values of the "ma" parameter [0.1,0.5,3]. Comment out the graphs 

1c) Write the code that calculates the axis regularity and phase spectra of the input, carrier and output signs for the value ma = 1 in the experiment. Plot the amplitude spectra of the three signs in a single image with subplot, delimiting the x-axis of the graphs with xlim [-3 * Fc 3 * Fc]. Make the necessary title and axis names for each image. Comment on the graphics
