I have used a multimeter to measure my phototransistor
and I got one excel file with time versus Magnitude.
But I got some noise, so I want to use Matlab to do FFT
from time domain to frequency domain(frequency versus magnitude) called Photorespone.
I attach my file as below.
I wanna make this kind of figure, freq versus amplitude.
