Wien Bridge with AGC 2

01:11:26

Simpler AGC :D not real though, but the only component that has any resemblance of a thermal coefficient is the motor here on EC. In reality, a bulb would have a thermal coefficient properties, so that when a higher voltage is introduced to the bulb, a lower resistance is produced by it. In EC, the motors have a time constant similarly, so it works in simulations with a close enough effect.

Especially in a vacuum space.

@wyoelk Bulbs are not in a vsccum space,. Probably you forget.

same result you get with an normal resistor no need for a motor. http://everycircuit.com/circuit/6460366113210368

Yes @Billy, that's correct. Type-o.

@Hurz, the motor should be able to work as an AGC here in EC. Can't get it to work though.

here the AGC regulating effect comes from the nonlinearity of the amplifier. without soft clipping (lower input amplitude) the gain is higher then with clipping, and if the gain is exact in the middle what it needs to be stable the output will be stable. Thats the nonlinear natur of amplfier. This motor regulating effect i wish you demonstrate in a very simple setup before you make use in a complex amplifier loop.
