MC1594 AC voltage multiplier circuit

This circuit is composed by four quadrant multiplier MC1594, the circuit issimple, the accuracy is a bit poor. In order to make the circuit works in linear area, input resistance R1 and R2's values depend on the input voltage's value. R1 equals to V1 multiplied by 6, R2 equals to V2 multiplied by three. If V1=V2=3V, then R1=18kΩ, R2=9kΩ.When there aredifferent input voltages, generally R1=52kΩ, R2=30kΩ, but that would make precision and linearity fell. The relationship of input and output is Vo=V1V2/10.
