the source of the 10V signal is from a air flow station which varies depending on the speed of the fan 30% speed = 3V, 60% speed = 6V, 100% speed = 10V. this signal is sent to a variable frequency drive that runs the fan and it needs to be stable, but what happens is that the voltage drops down to 0 for a split second, this happens unpredictably and frequently. i need a very simple circuit that would get rid of this voltage drop. something like the circuit for the fuel gauge in the car, all the fuel splashing around in the tank but the needle doesn't fluctuate.
thanks.
