Hi, So I'm trying to get the following waveform using amplitude modulation(the green one), Is the amplitude modulation equation used on waveforms the same as this one?
as it is now, it seems(if using the same equation as above) that it is assumed that a, as shown in the desmos graph in red, is always assumed to be 1 and can't be changed.
The modulated waveform i want to get is an arbitrary carrier being modulated by a sinusoid. Essentially i want to invert the carrier periodically and do so smoothly by sinusoidally changing its amplitude from 1x to -1x, so it would be like the purple equation, just multiply my arbitrary carrier by a sinusoid of any frequency i might need. I have tried doing this by getting the arbitrary data and multiplying it by the sinusoid on libreoffice calc, but for it to be low enough frequency for my purpose, i need to repeat the arbitrary points hundreds of times, so it doesn't fit in the wavegen memory. I tried doing it with the alter menu in the wave generator, but there is no way to tell it to fit the arbitrary waveform hundreds of times "under" the slow sinusoid, or not that i can find. I would like to know if there is currently a way to do this kind of modulation on waveforms, or if it would be possible to add an "a" setting to be able to achieve it in the way i do it on desmos.
Thank you!
