Plot a sine wave with the following... how to plot it?

Create a time vector, sine wave, 5 periods, 1 kHz, amplitude 2 volts in 5 x 1024 samples (time axis) as well as 5 periods in 4096 samples

What have you tried?

[Jayanta Deb]

t=[0:1:1024]; A= 2; f=1000; fs=5;

x=sin(2*pi*f/fs*t);

plot(t,x)

I am new so, I am not sure if it is correct with the context of the question?

Answer 1

[Rik]

You're very close:

freq=1000;%1 kHz
t=linspace(0,5,1024)/freq;%from 0 to 5 periods in 1024 steps
A=2;%amplitude
x=A*sin(freq*t*2*pi);
plot(t,x)

I don't really see how more samples will change things, but you can just change the linspace parameters.

BTW, for next time: have a read here and here. It will greatly improve your chances of getting an answer.

Answer 2

[SWETA K]

x=0:3.14/100:2*3.14;

y=sin(x);

plot(x,y);
