- Problem 1 We would like to build an AM radio receiver using a series RLC circuit to act as a bandpass filter as shown in the figure below. We have decided to use a 500 μH inductor, 25 Q resistor, and a variable capacitor whose capacitance can be adjusted between 20 and 150 pF. A radio “tunes” into a certain frequency by adjusting its receiver circuit so that it resonates at a specific center frequency with some amount of bandwidth. + vi(t) 1. Determine the range of channel frequencies that we can tune into with this receiver. 2. Determine the receiver's bandwidth. 3. AM radio broadcasting has assigned channels, which range from 540 kHz to 1700 kHz spaced at 10-kHz intervals. What is the largest value of the internal resistance R that would allow us to avoid adjacent channel interference (i.e., listening to more than one channel at once)?
