The resistor in Figure P33.55 represents the midrange speaker in a three-speaker system. Assume its resistance to be constant at 8.00 (. The source represents an audio amplifier producing signals of uniform amplitude ∆Vin = 10.0 V at all audio frequencies. The inductor and capacitor are to function as a band pass filter with ∆Vout/∆Vin = ½ at 200 Hz and at 4 000 Hz. (a) Determine the required values of L and C.
(b) Find the maximum value of the ratio ∆V out/∆V in.
(c) Find the frequency f 0 at which the ratio has its maximum value.
(d) Find the phase shift between ∆V in and ∆Vout at 200 Hz, at f 0, and at 4 000 Hz.
(e) Find the average power transferred to the speaker at 200 Hz, at f 0, and at 4 000 Hz. (f) Treating the filter as a resonant circuit, find its quality factor.
