Re: Using a Ring Modulator to extend the range of Osc

2002-08-18 by buechlerjoe

The A165 Trigger Modifier seems to be working okay as a frequency 
doubler in the audio range, but I don't have a scope and can't see 
how well it's holding up in the upper frequencies.

Another possibility would be to try AM using a VCA instead of the Ring 
Mod. This gives you both input frequencies in addition to the sum and 
difference, so you'd have to filter out the carrier frequency.
