The circuit as shown is composedof thevoltage-frequency converterand amplitude modulator. Input V1 controls the resistance of mosfet 2N4222 by operational amplifier A1. Soit can change the oscillation frequency of no steady-state much harmonic oscillator. A2 is an input signal amplitude modulator. The input signal V2 is output after being modulated.It setsthe clip broken voltage of mosfetas Vp, if (1+R1/R2)=Vp, then the relationshipbetween output and input is: Vo=-V2/V1. The range of V1 and V2 is 0~10V. Output Vo is an average value, which can be gotten from filter or damping type voltmeter.
