- 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.The input power of a filter is 200 mW and its output power in dBm scale is 20 dBm. Accordingly, a) Does this filter provide Attenuation or Gain in a circuit? Why is that? b) What is the value of the power loss or gain in this filter?We apply a 5-V-rms 20-kHz sinusoid to the input of a first-order RC lowpass filter, and the output voltage in steady state is 0.5 V rms. Predict the steady-state rms output voltage after the frequency of the input signal is raised to 150 kHz and the amplitude remains constant.

Justify your selections - What is the disadvantage of selecting the filter cutoff frequency, fc to equal the highest frequency output of the measured signal?What is the distinction in voltage attain of a lowpass filter if the enter frequency is doubled?
