Question

Second order circuit as a band pass filter.

1. Consider a series RLC circuit of your choice with AC source. Find the resonance conditions (resonant frequency, quality factor cut-off frequencies and bandwidth.

Simulate(multisim) the resonance condition by experimenting with AC signal of several different frequencies and comparing the output amplitudes. You need to show graphs of simulation with several different frequencies. Demonstrate that the simulation results confirm the calculated resonance effect.

Make a band pass filter from circuit in (1). Using appropriate simulation, build the amplitude and phase frequency response and find the filter parameters using it (all your findings should be clearly seen on the graphs). Analyze the results and draw conclusions.
