| Jan 12 at 2:04 | comment | added | Tom | Thank you. I understood the point. I was trying to calculate the PSD of a 10 second and 20 second sinusoidal signal using matplotlib.mlab.psd() function. I didn't understand why the magnitude of the PSD was different between those. I was confused with the difference of a radom signal and a sinusoidal (periodic) signal. | |
