Suppose, I have a 1000 seconds normally distributed time domain samples sampled at 500KS/s. Take fourier transform using window of 1 sec. Now, I have 1000 sets...

I know that for stationary data, the ACF function should die down fast. But I don't know how fast. How the significance level (95%) is calculated to compare if ACF...

Yes. Because bandpass filter will attenuate frequencies in the spectrum. I want to remove them from the spectrum.

1.jpgI have attached the Power spectral density of my underwater noise data (Sampling rate = 500K/S/s). I calculated this PSD by applying welch's method on the time...

Thank you so much for your reply. I understood the Welch's method and it is giving good results. It is basically averaging to reduce the variance of the periodogram....

Hi all,I want to compute power spectral density of the noise data. The underwater noise is measured at 500K Sample/sec for few hours. The overall data file is very...

Hey all,I have this code for cross correlation between two signals shifted by 90 degree and having some attenuation: fs=500000; t = [0:1/fs:0.001]; A = 2; f...

I want to plot the phase vs frequency plot using the sweep signal. My sweep signal looks like this: every cycle is of 1sec which is made up of 1msec sine burst...

I want to plot the phase vs frequency plot using this sweep signal. I am using correlation to find the phase difference between the received signal (from the RC...
