- 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.
