How would i go about creating this amp with a gain of 30. Resistors are no prob, but how would i find the gain with the capacitor and resistor in this differentiating amp?

What is the frequency at which you need a gain of 30?
The gain is simply the capacitor reactance at the design frequency divided by the input resistance.

The gain is simply the capacitor reactance at the design frequency divided by the input resistance.
So assuming there is no frequency as a dependant variable here, my gain would just be capacitive reactance/ value of input resistor?
I think the gain would simply be RC because the output function formula is the following.
\(v_o=RC{{dv_i}\over{dt}}\)
So, you need to find the best combination of standard resistor and capacitor values that gives you RC=30, as closely as possible.
I'm not sure I follow you. You need to know the input to calculate the output.How would the input and output voltage be found now, if neither are known to begin with?
