The Amplitude Modulation (AM) is a technique used in communication for transmitting information via radio carrier wave. AM works by varying the amplitude of the transmitted signal in relation to the information being sent. The equations of the carrier signal, the original signal to send, and the modulated signal combining the two signals are respectively: VI-Vc sin (2πfct) V2=Vm sin (2πfmt) V3=Vcsin (2πfct)+ Vm sin (2πfmt)* sin (2πfet) C Supposing that Vc =Vm=1, fc-20, fm 1. Write a MATLAB program that plots the three signals with single call, the graphs must be contain (desired title, axis labels, annotations, with symbols for color, style, and marker) for each graph. Use the step 0.0025 for the time.
