VCOs, an envelope generator, VCAs, a ring modulator, VCFs, sample & hold units, noise generator, an envelope follower, a mic preamp, a computer interface and some other circuits. The above FM transmitter design is a result of many hours of testing and tweaking. You can find many description of it out there. I'd really like to add a VCA and VCO next to really get this going, but I'm having trouble finding schematics for +/- 12V VCAs and +/- 12V VCOs based on the CEM3340. Braska is always in the mix. You can still look up all the schematics for befaco's stuff and a whole lot of Doepfer like the super saw and others. Explaining the Quantussy Schematic By Richard on November 22, 2015 You can find a lot of posts here, under the cocoquantus and the quantisise tags, where I have explained the architecture of the five oscillator cluster in the Cocoquantus. A voltage-controlled oscillator or VCO is an electronic oscillator designed to be controlled in oscillation frequency by a voltage input. Gray and Meyer, 10. •Hartley- The resonant circuit is a tapped inductor or two inductors and one capacitor.
