Chapter 10, Problem P10.6-6

(choose chapter or problem)

P 10.6-6 Using a tiny diamond-studded burr operating at 190,000 rpm, cardiologists can remove life-threatening plaque deposits in coronary arteries. The procedure is fast, uncomplicated, and relatively painless (McCarty, 1991). The Rotablator, an angioplasty system, consists of an advancer/ catheter, a guide wire, a console, and a power source. The advancer/catheter contains a tiny turbine that drives the flexible shaft that rotates the catheter burr. The model of the operational and control circuit is shown in Figure P 10.6-6. Determine v(t), the voltage that drives the tip, when \(v_s=\sqrt{2} \cos \left(40 t-135^{\circ}\right) \mathrm{V}\).
