the voltage is the baising voltage of an Avalanceh phorodiode and the freq is depend on the photon coming to photodiode.
maybe my question is so basic but can u show me one simple op-amp circuit which can do this function?
Hi,
I am looking for a level shift which shifts an analog circuit with a variable ( tunable) DC level.
means for example I can change the analog voltage with 15volt once, and next time may be -10. the range of change for the DC is (-20 to 20).
Another solution could be adder; to add the...
