<div dir="ltr">I find this a bit misleading. Ring Modulation is when both singals are bipolar and that's it. And he's saying something is AM modulation when it's Ring Modulation (but he doesn't say it is so and specifies Ring Modulation as something else). It doesn't hurt to be more accurate. Curtis Roads' Computer Music Tutorial makes it very simple and straightforward.</div>

Hi,<br>
Most of the AM examples are simply multiplying carrier and modulator outputs, which is also known as Ring Modulation. But in the resulting spectrum the carrier is gone and only the side bands appear. I couldn’t figure out a way to keep the carrier signal in the resulting spectrum (Like as in real AM, not RM).<br>
<br>
It was easy in Csound for example, since the amplitude value is an input parameter to the oscil function.<br>
<br>
Any ideas ?<br>

Do it the same way as in analog, add a DC offset to one of the signals.<br>
