Differences in DFT of phase shifted sinusoids [3 articles]
alicec - 2012-04-24 16:09:00
Hi,
I've been looking into a particular problem for a while now and I have yet
to come up with an answer from the literature.
Does anybody have a mathematical explanation of the why abs(S) and a...

i doing the project AM-SSB modulator using code composer studio
TMS320C6713. And is almost finish but the output samples have some
problem and i found the problem is how to make the input samples re...FFT Interpolation of complex numbers [7 articles]
Lightbulb85 - 2012-04-24 04:07:00
Hi,
I have been using a relatively small (256 point) FFT and some interpolation
to estimate the actual input frequency when I do not have a bin at exactly
that frequency.
However I was wondering i...Zero padding effect on frequency domain correalation [2 articles]
hokselato - 2012-04-23 18:11:00
Hi,
I am trying to make correlation on correlation on frequency domain and I
use fft function which takes power of 2 input data so I must pad with zero
my incoming sample signal and localy generate...Printing threads in this forum [2 articles]

Just a request: I wish it could be easy to print a given thread in a text
format. Right now I could only print from the browser, or copy and paste
the text to a Word Doc.
Thanks for considerations...Linear prediction optimization?
Aikku - 2012-04-23 04:32:00
Hey guys.
So far, I've posted on a forum and a mailing list with no results, and only=
just realized it's probably best to ask this question on a DSP-specialized=
group.
(Sorry that my first...Shifting FIR frequency centre [24 articles]
kaz - 2012-04-21 11:25:00
You design a linear FIR(symmetrical real coefficients) then you decide to
move its frequency centre. The new FIR (complex) may not maintain symmetry
of its real part or imaginary part or both. Its gro...gardner timing and farrow interpolator [13 articles]
jacobfenton - 2012-04-20 16:21:00
I am investigating symbol timing recovery, specifically the gardner timing
recovery method with a farrow interpolating filter. In some block diagrams
I have seen in my research, there always seems to ...Low frequency component from FFT? [3 articles]
jski - 2012-04-19 15:24:00
As a DFT/FFT newbie I have a (probably naive) question: I was asked to
use an FFT to find the low frequency term in data collected from an
accelerometer. I used the routines in FFTW appropriate for ...How to solve Reigh Quotient type problem? [2 articles]
