Hello to everyone. I have one noisy signal, and this signal is in the time domain. I want to draw this signal through the Fourier transform. As a result, what I expect is a Gaussian dispersion around 0. However, I don't know how to apply and draw the Fourier transform on my signal. I would be glad if you could help.

signalplusnoise=1x674

signalplusnoise=[0.0161,0.0308, 0.0112, ..., 0.3827]

hello

see below a code to do spectral analysis (example)

but to me you're confusing fft with histogram. The fft spectrum will give you the amplitudes of the noise frequencies and they all will be positive and spread across the frequency range from zero to Fs/2.
