Convert the continuous signal described by y(t) = 10*sin 2*pi*t * into a discrete set of eight numbers (N=8) using a time increment of 0.125 s.

f=1, N=8, ts=0.125s

Code you help me to code this in matlab?

Thanks,

I want this resutls as shown below.

I have coded this but since you said you want help to code this, first please provide the code that you have attempted. Because this question seems to be a homework question that you have directly asked.

Hi Syed,

Inorder to plot the signal, you have to first define discrete time instances and signal values. Time vector can be defined as:

t=0:0.125:N*0.125;

where N = 8 as per the question. Substituting 't' into 'y(t)' should give you corresponding discrete signal values. You can input 't' and 'y' vectors into 'stem' function to obtain the plot.
