ideally, what should the reactance of a bypass capacitor be in order to eliminate a 10 kHz AC voltage at a given point in an amplifier circuit?

DP6.1 The control of the spark ignition of an automotive engine requires constant performance over a wide range of paramelers [15]. The control system is shown in Figure DP6.1. with a controlter gain K to be selected. The parameter p is equal to 2 for many autos but can equal zero for those with high performance. Select a gain K thal wil result in a stable system for hoth values of p. FIGURE DP6.1 Automobile engine control. 5 K Y(s) R(x) s + 5 s + p -1/5

What circuit compensates for the greater frequency deviation at the higher modulating signal frequencies?

d) A regulator as shown in Figure 4 has an input voltage, Vs 12 V. The duty cycle, k = 0.35 and the switching frequency is 30 kHz. It also has an inductance, L= 200 µH, filter capacitance, C = 440 µF. The average load current, la = 1.25 A. Determine the; i. average output voltage, Va. ii. peak-to-peak output ripple voltage, AVc. iii. peak-to-peak output ripple current of inductor, AI. iv. peak current of the transistor, Ip. v. critical values of L and C. vi. critical values of L and C if Vs is increased to 14 V. Estimate the change in percentage for the critical values of L and C. V, Load V V G Figure 4
