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....

Power spectral density

New thread started 6 years ago
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...

Bode plot analysis

New thread started 6 years ago
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...
Hey all, I am generating the burst of sine wave of 5 volt and sending it over analog output channel of my Ni USB 6356 board. This signal is transmitted to the input port...
