Design a parallel resonant circuit for an AM radio receiver. The inductance can vary to adjust the resonant frequency in order to cover the full AM broadcast band, which is from 530 to 1610 kHz. The circuit bandwidth must be at least 20 kHz in order to reproduce the full station signal, but not too much more than that in order to filter out adjacent stations. The resistor value is 33 kΩ. The inductance varies with a fixed inductor Lfixed in series with a variable inductor that has a range from zero to Lvar in order to cover the broadcast band. Using standard 20% tolerance commercial values, obtain the value of the capacitor and the two inductors. Finally, determine the quality factor range of the circuit from the low end to the high end of the broadcast band. Given: w = 2pif, w0 = 1/sqrt(LC), B = w0/Q, Q = w0RC
