ET115 WEEK 7 LAB 1. Watch the Week 7 Lab Video - Resonance (11:49) Part 1 Series Resonance 2. For the figure below, design a resonant circuit that has a center frequency of 10KHz with a bandwidth of 2 KHz +/- 200 Hz for the voltage across R1. The input voltage should be 5 Volts peak. a. Show all the calculations to develop the component values for R, L, and C. Indicate any assumptions. b. Run an AC Sweep Analysis for the voltage across the resistor and use the cursors to locate the values for the center frequency and half power points. Show screenshots showing the frequency response along with the date/time stamp of the simulation. c. Do a Single Frequency Analysis at the resonant frequency to get the component voltages, phase, circuit current, and impedance. Capture a screenshot of the response showing the date/time stamp. d. Do a Single Frequency Analysis at 7 KHz and 13 KHz to get the component voltages, phase, circuit current, and impedance. Capture a screenshot of the response showing the date/time stamp. e. V1 C1 H L1 R1 Part 2 Parallel Resonance 3. For the figure below, design a resonant circuit that has a center frequency of 50KHz. The input voltage should be 5 Volts peak. The goal is to block a 50 KHz signal from the input to the output.
