I have time domain history data. Then, I change it into FFT to get the frequency domain. After that,I am going to get the bandwidth of my FFT data. My coding is:-
signalx = Ch1_1; N=6678; zx = fft(signalx); plot(1:N,abs(zx)); plot(20*log10(abs(fft(zx))));
Can someone verified the coding?Is it true?Attached the figure of my bandwidth data
