Problem #2
A radio receptor is often disrupted by 8 kHz whistle. Design a "whistle-stop" filter that has a bandwidth of 1 kHz and uses 33 nF capacitor.
b) The previous example is ideal and will completely eliminate the 8 kHz whistle. However, circuits are not ideal so let’s assume that the inductor has 2 Ω resistance and the source has 50 Ω resistance. If the filter specification calls for -18 dB, will the specification be met?
Need a hint?
Design the circuit with a series RLC circuit and the output voltage is across the inductor and the capacitor.
