I want to design a circuit which takes two analog signals with a DC-offset via koax inputs, and forwards them.
In between the voltages should be capped at a user-defined level (between 200 mV and 500 mV), if the input voltage is higher, then it should be capped at the cutoff level. The reaction time of the circuit should be as fast as possible. The input signals have a frequency up to ~2-3 kHz. What is the best way to achieve that?
Bonus: Amplification of the signals in the circuit is also possible.
