## Equation for Square law circuit modulator

For DSBFC AM (double side band full carrier Amplitude modulation ) The message signal m(t) must be multiplied by carrier maybe $$Ac*cos(\omega_c(t))$$ (For modulation) This modulation is done in reality by using the non-linear characteristics of the diode,where $$i(t)=av + bv^2$$ v=applied voltage to diode Here we apply$$v =Vc(t)+Vm(t)$$  […]
