A biomedical transducer can be represented by a series RLC circuit with a 100 ohm resistors andunknown capacitor and inductor. Analysis of the transducer in the lab indicated that the dampingcoefficient is 0.4 and natural resonance frequency is 159 Hz. Determine the values for thecapacitive and the inductive components. Discuss the way to increase the damping coefficient to0.707 without affecting the natural resonance frequency.

This is a practice question from my Introduction to Circuits course. I am having a hard time finding the poles for this. When I implement the circuit in LT Spice, I can see that the cutoff frequency is somewhere around 16kHz, but I can't figure out how to come up with that value mathematically. It is underdamped; so, will have imaginary components, but I'm lost as to how to find them or what to do with them or how to come up with the correct cutoff frequency to match LT Spice. Thank you for your assistance.
Problem C:The gain for the circuit shown is 85% atfrequency f1 and 95% at frequency 2.(True or False) Frequency f2 is higher than f1.Problem D:Resistor R is replaced by a resistor that is half the value of R. Will the 3dbfrequency decrease? Problem E:In a certain application it is desired to increase the passband of the circuit.There is a capacitor of the same value available. Can this extra capacitorbe used to accomplish the task, and if so, how would it be used?
