Hi Minhas,
To analyze your lab data:
- Firstly you can use the `plot` function to draw time (x-axis) versus each voltage signal (y-axis).
- Next, you can go for `plot` again for the frequency-domain by plotting frequency (x-axis) against FFT magnitude (y-axis) for each signal.
- You can also overlay multiple signals on the same time plot for comparison.
- Optionally, use the `spectrogram` function to show how frequency content changes over time.
These steps help you examine both time and frequency aspects of your signals and check if your sampling frequency is adequate.
I hope this helps!
Thanks
