hi there, im new to this forums, so i would like to say hello to everyone! i have been using this forums to answer my questions for some time and have found most of them on this forums, so i would like to say thanks to you guy!
i have one question which i am stuck on, this question im doing is revision for my exams, i would like guidance on how to go about answering the question.
Question:
a signal x[n] consists of signal complex exponential of frequency ω. Evaluate the sequence:
{x[0], x[1], x[3], x[4]}
and calculate the 4-point DFT when the frequency of x[n] is:
ω = ωs/4 i.e ¼ of the sampling frequency
i know that :
ωs = (2Π)s/T
but i dont know what to do next...
if someone can help i would appreciate it....
thanks in advance
pure!
