If we have data such as time (s) and Knock sensor Signal (V), how can we convert them to Frequency and Amplitude?
Dear Chivon Choeung ,
please 'google' for that topic; there will be a lot of results, for example:

It is better to use Matlab
Thank you so much for these questions. I have found the solution.
In the case of UPS applications and Motor Control, which is better between Continuous Control Set-Model Predictive Control and Finite Control Set-Model Predictive Control?
