Hw Assignment 3
Determine the dc voltages, VB, VE, and VC, with respect to ground in Figure 374.
Vb = (4700/ (22000+4700) x 15= 2.64 V
Ve = Vb Vbe = 2.64 0.7 = 1.94 V
Ie = 1.94 / 390 = 0.00497 mA
Ie = Ic
Vrc = 0.00497 x 1000 = 4.97 V
Vc = 1

1. What is the exact value of IC for IE = 5.34 mA and IB = 47.5 A?
Ie= Ic+ Ib
Ic= Ie Ib
Ic = 5.34 0.0475 = 5.2925
2. A certain transistor has an IC = 25 mA and an IB = 200 A. Determine the DC.
DC= 0.025A/0.0002A = 125 A
1) Figure 641 shows the output voltage of an op-amp in response to a step input. What is the
Slew rate = (12-(-12)/ 15 = 1.6
2) How long does it take the output voltage of an op-amp to go from 10 V to +10 V, if the slew
rate is 0.5 V/s?
1. Identify each type of filter response (low-pass, high-pass, band-pass, or band-stop) in Figure 9
2. A single-pole high-pass filter has a frequency-selective network with R = 2.2 k and C =
