Amplifiers

Explanation of question 14

  1. i and ii are both true
  2. i is true but ii is false
  3. i is false but ii is true
  4. i and ii are both false

The answer is :- 2 Being rich in harmonics, class C amplifiers are ideal for use as frequency multipliers. As a frequency tripler, a push-pull circuit is often used—but not for an even number (e.g. doubler).
