    Crutschow,

    It would be nice to be as fast a possible. Closer to the 1 uS range instead of 35 uS? :)

    Closed: Photocoupler Saturation?

    Hello everyone!

    There is a photocoupler (LTV-817) that I am using that is seeing a power glitch (~1 microsecond) and it seems to take a long time for the photocoupler to recover (~35...

    Closed: Re: Impedance Calculation

    Thanks for the posts everyone. A follow-up to what BradtheRad posted.

    My follow-up question is that if Vout is a percentage of Vin how do I know what this percentage is? Do you mean the transfer...

    Closed: Impedance Calculation

    In the attached image I am showing a voltage divider with the values of 50M (fixed) , 4.7k (fixed) and an unknown impedance Z.

    Is it possible to calculate the value Z only using Vin, 50M and the...
