a. Determine the levels of lc and VCE for the network of Fig. 4.121.

b. Change β to 135 (50% increase), and calculate the new levels of IC and VCE.
c. Determine the magnitude of the percentage change in IC and VCE using the following equations:

d. Compare the results of part (c) with those of Problems 11 (c), 11 (f), and 20(c). How does the collector-feedback network stack up against the other configurations in sensitivity to changes in β?
