a. Determine I_C and V_CE for the network of Fig. 4.118.

b. Change β to 180 and determine the new value of I_C and V_CE for the network of Fig. 4.118.

c. Determine the magnitude of the percentage change in I_C and V_CE using the following equations:

d. Determine I_C and V_CE for the network of Fig. 4.122.

e. Change β to 187.5 and determine the new value of I_C and V_CE for the network of Fig. 4.122.

f. Determine the magnitude of the percentage change in I_C and V_CE using the following equations:

g. In each of the above, the magnitude of β was increased 50%. Compare the percentage change in I_C and V_CE for each configuration, and comment on which seems to be less sensitive to changes in β.
