Hi,
So i am in a fix now. I have a discrete time signal which is produced by a device with Nyquist frequency as 50MHz and 1088 samples (there is nothing i can do with the device to change the frequency or number of samples). I have an analytical signal which is produced in the frequency domain by modeling in the frequency domain with the Nyquist frequency as 50 MHz and 2176 samples (the number of samples was higher so as to reduce aliasing while carrying out an inverse fft). Now I need to deconvolve these two signals in the frequency domain to have an idea what affect the electrical system has and to introduce this into the analytical model. So the deconvolution takes place using a weiner filter.
1. I just want to know how do i deconvolve these two signals of different lengths?
2. Also in the experimental signal, I want to just take the signal for the first 8 micro seconds so around 400 samples. So can i just pick out the first 400 samples from the time domain and fft it and deconvolve with the 1st 400 samples of the analytical signal?
Any help will be appreciated
Thanks!
