For an AM superheterodyne receiver, station A with RF signal of 1000 kHz uses high side injection to receive the signal. A tuned circuit for a bandpass filter has inductor coil, L= 25 µH, resistor, R = 20 Q and capacitor, C = 4.894 nF. (i) Determine the center frequency of the bandpass filter. (ii) Determine the quality factor of the tuned circuit. (iii) Determine the bandwidth of the bandpass filter. (iv) Find the upper and lower cut frequency for the bandpass filter. (v) Plot the 3 dB bandwidth of the bandpass filter.
