(choose chapter or problem)

Consider the circuit in Fig. 17.45(a), first without tapping the coil. Let L = 5 H and assume that R1 is fixed at 1 k. We wish to design a tuned amplifier with f0 = 455 kHz and a 3-dB bandwidth of 10 kHz [this is the intermediate frequency (IF) amplifier of an AM radio]. If the BJT has Rin = 1 k and Cin = 200 pF, find the actual bandwidth obtained and the required value of C1.
