TRUE/FALSE. Write 'T' if the statement is true and 'P' if the statement is false.
1) The dc load line is a straight line drawn from /C(sat) to Vcc-
2) The Q-point can be anywhere along the dc load line.
3) Voltage-divider bias requires two power supplies.
4) Base bias is more stable than voltage-divider bias.
5) Collector feedback bias uses a form of negative feedback
6) IC and E are nearly the same in a properly biased transistor.
7) VBE of properly biased pop transistor is a positive value.
8) RIN(BASE) will increase if lε decreases.
MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.
9) Assume the output of an amplifier has both peaks clipped. This can be caused by
A) too little gain
C) power supply voltage is too high
10) At cutoff,
A) VCE = 1/2 VCC
B) VCE - VCC
B) Q-point is not centered
D) all of the above
10)
C) VB = 0.7 V
D) IC - IC(sat)
11)
11) Assume a load line is drawn for a transistor amplifier. If VCC is increased, the load line will
