How to obtain FFT for the given amplitude (vs) time plot?
Kindly inform me is below code is right ?? as I don'see any FFT peaks in the figure 2?
% 200 kHz frequency load and the length of time signal is till 10761 as shown
% provides time(vs) amplitude values
E = load ('5200D1218');
%Fs = 200*10^3; %frequency load used 200kHz
T = E.data(1,1).vectorza(1,1:10761); % time
P = E.data(1,1).Amplitude(4,1:10761); % amplitude values obtained
%now to plot FFT for the amp(vs) time results
p = fft(P);
