INTRODUCTION
If you were to make a quick review of the subjects discussed in this module up to this point, you
would see that you have been given a considerable amount of information about amplifiers. You have
been shown what amplification is and how the different classes of amplifiers affect amplification. You
also have been shown that many factors must be considered when working with amplifiers, such as
