Dual four-quadrant multiplier with VC Offset
This unit does an analog multiplication of two signal (A and B) and add an offset (C).
Signal B has a attenuverter that will multiply by -2 to 2 while Offset has a -1 to 1 attenuverter (unity gain).
B and C inputs are normalized to 5v and 10v so A input can be processed just using the potentiometers.
The output of first block is normalized to second one so second output can act as master, to get (A1B1+C1) + (A2B2+C2)
It can act as a dual voltage controlled attenvuerter, dual ring modulator, dual VCA or four channel mixer.
Available as an assembled Module and as a DIY project.
