AM wave

[anny321dum]

Can please somebody check my code and tell me what I ma doing wrong. I am trying to write a code for AM modulated wave of amplitude A to plot N element array of displacement values. I am writing this code in MATH Script.

The code is

delta_t=1/f_s
start=0
step=t
stop=(N-1)*delta_t
t=start:step:stop
A=input('enter amplitude of the wave');
fmod=input('enter modulation frequency');
fsig=input('enter signal frequency');
ym=A*sin(2*pi*fmod*t);
ys=sin(2*pi*fsig*t);
y=(A+ym)*sin(2*pi*fsig*t)
subplot(3,1,1)
plot(t,y);

You have step = t, do you want to have step = delta_t?

I have written a MATH script code to plot the AM wave. I think there is some error, because I am getting a straight line instead of wave pattern.

Thanks in advance for your help
