Adding waveform in matlab

Hello,

Good Day Everyone!

I would like to manipulate waveforms in matlab. For example, I have a fundamental frequency of 220v at 60Hz, and a 50th harmonic frequency of 500v at 3000Hz.

I would like to add these following signals and plot the resulting waveform, some sort of before and after waveform. Is this possible to do in matlab? If yes, what particular topic is this in matlab so I can study on it.

Thank you so much!

it's going to look noisy, the amplitude of the harmonic is more than double the amplitude of the 60Hz. Who is the carrier, 60Hz or 3kHz?
