Amplifiers

Explanation of question 10

Two transistors are connected in push-pull configuration. The output waveform will

  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 :- 4 Push-pull restores the complete cycle. The second harmonic is substantially reduced, but odd harmonics (as opposed to even) are still present.
