A lossless LC circuit can be used to provide controlled oscillations to generate a controlled frequency for wireless communications. (a) Design an LC circuit with amplitude of 5 V and frequency of 400 kHz, where the largest possible inductor available is 400 nH. Now suppose that you have an undesired resistance of 0.2 mΩ in series with the LC oscillator. (b) Determine if, and how much, the frequency changes as a result of the resistance. (c) Determine the maximum time that the oscillator can run before the voltage amplitude decays to 4.8 V, and (d) determine the energy dissipation during this time period (it will be very useful to use software such as MATLAB for calculating the energy dissipation!).

- Problem 1: Design a high-pass filter with a corner frequency of approximately fc = 200Hz. Your filter must ensure that at least 90% of the incident signal power is attenuated at f = 60 Hz. Verify the proper operation of your filter by using LTspice XVII to plot the magnitude and phase response of the voltage transfer function H(f). Show LTspice XVII Part if possible.

If a current has a negative value, then the reference direction chosen was incorrect and the current is positive in the opposite direction. Your answer can be the negative value – i.e. you find that 12 = -1mA.
