In a periodic waveform, how to know how many harmonics it has and how to determine its fundamental frequency. Then remove his harmonics through filtering? I don't know much about this, thank you all.
Can matlab do these?

Using an oscilloscope,

The oscilloscope has an FFT, you can directly see the amplitude of each frequency band.

I know that matlab can be done, but it is not very useful. The frequency of the square wave is the frequency of the first harmonic.

This is generally done through Fourier transform. There are related Fourier calculation functions in matlab. Just enter your parameter values directly.
