H11P1: LC TANK
In the space provided below write an algebraic expression in terms of the device parameters for the bandwidth Δω of the impedance Z looking into this tank circuit.
correct
1RC⋅C+RLL
The antenna tank of a Graymark 536 Radio Kit has an inductance L≈0.65mH. The resistance of the inductor RL≈4.0Ω. The equivalent resistance across the capacitor is RC≈490.0kΩ. The capacitor is variable, for tuning.
If we tune to a station at f=1010.0kHz what is the capacitance, in picoFarads, of the tuning capacitor?
What is the bandwidth, in kHz, of the tank at f=1010.0kHz?
