Figure 31.12a shows the crossover network in a loudspeaker system. One branch consists of a capacitor C

Question:

Figure 31.12a shows the crossover network in a loudspeaker system. One branch consists of a capacitor C and a resistor R in series (the tweeter). This branch is in parallel with a second branch (the woofer) that consists of an inductor L and a resistor R in series. The same source voltage with angular frequency Cd is applied across each parallel branch.
(a) What is the impedance of the tweeter branch?
(b) What is the impedance of the woofer branch?
(c) Explain why the currents in the two branches are equal when the impedances of the branches are equal.
(d) Derive an expression for the frequency f that corresponds to the crossover point in Fig. 31.12b.
