Unsure about RLC low pass transfer function
I'm unsure about the RLC low-pass filter transfer and frequency response functions I've been trying to calculate.I need $$ H(s)=\frac{Y(s)}{X(s)} $$ where x(t) is Vin and y(t) is Vr. I calculated...

How to "approximately" get the transfer function for a two-stage op-amp circuit?
One way to solve the above circuit is to write KCL equations and solve, but it is too lengthy. Another way is to look at the circuit for high frequency and low frequency and find the poles and zeros...

Cascading op-amps
I am trying to figure out the gain of the following circuit:What I have done so far is looking at each amplifier independently:$$U_3=-R_9/R_8=-4$$$$U_4=R_{10}+R_{11}/R_{10}=3$$$$V_o=-R_9/R_8 \times...
