What do I look for in a post? Clarity and Contribution.

NO vote: If the post is clear, but makes no contribution OR if the post is unclear, but makes a contribution (though I will try to improve the clarity either by comments or direct edit).

UP vote: If the post is clear and makes a contribution.

DOWN vote: If the post is unclear and makes no contribution (though I will try to see if I've missed something by commenting).

comment Frequency Spectrum with c++
The "spectrum" is frequency vs power / amplitude. The "spectrogram" is a completely different thing that shows how the frequency content varies with time.

comment Frequency Spectrum with c++
v[i] is a frequency-domain variable. It makes little sense to try to plot it against time.

Yes, thats much more like it.

comment Frequency Spectrum with c++
You probably don't want to plot it on a logarithmic scale. Values very close to zero (as you have around zero frequency) will completely obliterate the actual useful signal.

comment DFT calculation for different sampling Frequency
Welcome to DSP.SE! Are you confusing "signal frequency" and "sampling frequency" ? In most systems, it's hard for the sampling frequency to be changed dynamically... and also usually undesirable. If your sampling frequency is 800Hz, then any signal with frequencies less than 400Hz can be adequately (baseband) sampled.

comment Apply the Hamming window to a sinusoidal signal
If you're using matlab N = length(signal) should tell you. Or perhaps I don't understand what you're asking? In the example you give, N = windowsize (the length of your loop).

comment Proof from wave equation of upper limit of active noise cancellation
Regarding the latency (non-)issue: It is perfectly possible to generate zero latency discrete time filters. The technique is a little complicated, but it has been implementable in real-time since, oh, 1995 or earlier (though probably not in something that you could wear on your head back then! ;-) ).

comment Are there any US banks that allow you to make an international wire transfer online?
I second US Forex! But there are others that are cheaper and easier to deal with than most banks.
