Hi ,
I had the following doubt in dtft of rectangular pulse :
When we take fft of a rectangular pulse say h(n)=1 for n=0 to N-1.
Then in some books i reffered give the dtft as sinc function only. But why don't they consider the exponential term with sinc function.
Thanks and regards,
Pratham
Hi albbg,
The solution for this says as : X^f(w) must be 2pi periodic if X^f(w) is dtft of x(n), but cos(0.5pi n) is not periodic,so dtft is not possible. Can you clarify this statement.
PS:w belongs to R i.e Real value
Thanks and regards,
Prathamesh :-)
Hello,
A bandlimited analog signal is sampled (with no aliasing) at 500 Hz and 980 samples are collected. The DFT of these 980 samples is
computed. Find the value of the spectrum of the sampled signal at 120 Hz ? (a) Which DFT index k is nearest to 120 Hz, and what is its physical
frequency in...
