Problem statement: For one of your circuits, you must use an inductor in your filter design. (1) Assume you are working for a communication company which using up to 100Hz to serve your customers, while another company is sharing the same transmission line to transmit 1kHz and greater. You need to design a circuit to filter out other company's signal and deliver the desired signal. Note: In this lab exercise you may assume both signals are sinusoidal. And you need to pick a frequency for the second company's signal for this lab. (2) Assume you are working for the second company from part 1 instead. Design a circuit that will remove the low frequency signal and pass the high frequency signal you picked in part 1. (3) Quality factor for single order circuits is given as Q R WRC Calculate the quality factor for each circuit. Be sure to measure resistance of your inductor and include it in your calculation. Use the components provided in your kit. For frequency domain analysis, you can use the VAC source in LTSpice. Perform both transient and AC simulations in LTSpice. Try to make your transient simulations look as much like the 'screen shots' captured in the lab (similar scales, run times, etc.) to make comparison easy.
