new audio preamp suffers from 60 Hz hum from the powerline. Assuming that the desired audio frequencies are greater than 500 Hz, design a filter that goes between the audio source and the preamp (as shown in the picture). To keep things simple, design a filter using ONLY ONE resistor and one inductor. Determine appropriate values for these components such that the filter has 15 dB attenuation at 60Hz. show your work/thought process please.

Design a “rumble” filter for audio. It should pass frequencies greater than 20 Hz. Assume the source impedance is zero (that is, the voltage supply is perfect) and 10K minimum load impedance (which means the load could be variable and have a much higher impedance). Make a figure showing the expected output of the filter designed.
