Below is the graph of my load cell readings at 3 samples per second. I have collected 500 such samples. I want to stabilize the readings and read that first approach is to convert time domain data to frequency domain. I am new to DSP, so i seek your expert guidance on this.
My main aim is to stabilize the readings so that i can increase an accuracy of my measuring device.
Y = fft(y,251);
Why the author has taken 251 ? Any special reason? $\endgroup$ – Nimit Vachhani Feb 23 at 5:47Y = fft(y,500); Pyy = Y.*conj(Y)/500; f = 3/500*(0:127); plot(f,Pyy(1:128)) title('Power spectral density') xlabel('Frequency (Hz)')
