As part of a radio receiver, you are asked to design a simple bandpass filter using a series inductor, capacitor and resistor. The filter needs to pass a centre frequency of f0 = 1089 kHz with a bandwidth of 9 kHz. Do this by finding the capacitor and resistor values together with a 240 uH inductor that will give you the correct centre frequency and bandwidth. Also, calculate the quality factor Q for your filter. Sketch the filter circuit and show all your calculations.
