I have a set of data in excel like this:
column A is time in ns and column B is the electric field strength. now I want to convert the time-domain signal from these data to a frequency-domain signal with DSP toolbox in matlab.
to calculate Fs (sampling frequency) in order to use in signal analyse i use this formula:
time = T(:,1); L=2033; Ts = mean(diff(time)); Fs = 1/Ts;
which leads to :
then I import the signal (E) with sampling frequency Fs in signal analyze toolbox. my signal is like this:
now i want to apply a bandpass filter in 16-32 MHZ range , so :
I've increased the paging file to maximum on my system with no success! I should say that my system configuration is like this:
i5 CPU at 2.5 GHz
8 GB R3 Ram at 1600 MHz
I have two specific questions:
1- what should I do? Is there any thing that I should do to to be able to design the filter on my system?
2- if I change the time to second and the frequency to hz , how much does the results change?
