I am trying to convert my fft signal into PSD(Normalized) vs Freqeuncy (Hz) but can't get it right. I want to get some thing like shown in the figure. I found these figures in the literature. How to plot this in matlab? PSD from 0-1 and frequency in log scale.
If some one can explain with a...
why do i have a peak at 200 HZ? Please explain this?
Just one correction in last fft figure that the frequency units are KHz and not Hz
Total number of sample points are 500
Hi
I have a signal shown in the attached figure and the fft of that signal as well. In addition I have also attached the fft of the static noise signal. You can see that in the original signal there are harmonics present specially on the first half of the curve. I really dont expect them coz in...
