PLEASE THIS IS MATLAB EXERCISE :

Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal, as engineer you are tasked to use MATLAB to. simulate a conventional amplitude modulation (AM). USE a WHILE LOOP or For loop and, if-elseif-else statement to calculate the function Write a script named Am that will return the value of Am(t) for a given input value of t. Note that here the input argument is a real-number scalar value The piecewise function Am(t) is defined below: Where m(t) is message signal c(t) is the carrier Am is the modulated signal given by: Am(t)=m(t)c(t) The message signal is: m(t)=+2,4,0,0t
