The signal I have attached like this. If I give the L value is equal to length of time, the value is 1501. But frequency matrix is coming 1 by 751. So for this plotting issue is coming. Phase part i am unable to do.
So, what will be the correct code for frequeency, amplitude and phase?
I have tried to do it with this code
Time= 0:2:3000;
tt=time;
ss=signal;
Ts = mean(diff(tt)); % sampling time
Fs=500; %sampling frequency
Fn=Fs/2;
L=length(tt);
Y=fft(ss);
P_amp=abs(Y/L);
f=Fs*(0:(L/2))/L;
