You want it to be bipolar for both signal and modulator domains. So that:
+1 * +1 = +1 -1 * +1 = -1 +1 * -1 = -1 -1 * -1 = +1 A linear biased transistor and most simple op-amp circuits can't give you this. Hence the need for something like the CA3080 transconductance circuit. If you just need basic ring rod (positive domain only) then a simpler circuit will do On Thu, 3 Feb 2011 17:17:01 -0500 (EST) Mathieu Bouchard <[email protected]> wrote: > On Thu, 3 Feb 2011, Tyler Leavitt wrote: > > > My question is what would be the hardware equivalent of the [*~] object. > > I guess it don't have to be digital... even an analog equivalent would > > help me understand it better. > > Isn't the transistor related to [*~] ? > > But it depends which case of [*~], I suppose.
