This chapter has presented information on video and rf amplifiers. The information that follows
summarizes the important points of this chapter.
A FREQUENCY-RESPONSE CURVE will enable you to determine the BANDWIDTH and the
UPPER and LOWER FREQUENCY LIMITS of an amplifier.
The BANDWIDTH of an amplifier is determined by the formula:
