Reduce the circuits and calculate the natural frequencies (ω0) and damped resonance frequencies (ωd) for both circuits.  In an image come support formulas

A very common problem in instrumentation is that of interference of the telemetry that is to be measured. One of the primary sources of the interference is the power line. This is particularly true for high impedance circuits. Another path for this noise is ground-loops. One possible solution is to use a notch filter to remove the 50HZ component. Design a suitable notch filter for this purpose.

For the following circuit, C=1μf . Select the values of R and Rf to have a passband gain of -15 and a corner  frequency of 200 Hz. Enter the value of R1 in ohms.   Enter the value of Rf in ohms.   For the same circuit schematic above, let Rf=10kΩ. Now select the values of C and R1 to have a passband gain of -10 and a corner frequency of 100 Hz. Enter the value of C in μf but omit units.   Referring to problem 3, enter the value of R1 in ohms but omit units.
