Hi guys, i'm a bit embarassed that my first post here is in this section, but i'm taking a Elec. Eng. course abroad, which is out of my confort zone (i'm majoring in automotive eng.) and i'm trying to solve a few model problems. This one in particular deals with the DFT. Anyway:(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Consider the signal: y= 2*sin(1.5*2*pi*t)

the signal is sampled with a sampling frequency fc=8 Hz, for a time of 1 second and using a rectangular window. plot the modulus of the Discrete Fourier Transform.

-----------

I'm completely lost... I think I have to determine N, using the fc and sampling time, so something like this:

fc=8 Hz => 8=1/T and therefore T(sampling time) = 1/8 s

Since the total sampling time is 1s, for 1s we have 8 samples and so N=8 ?

Is this correct, and if so, where do I go from here?

Thanks!
