# Oscillators

### Explanation of question 8

- i The frequency of a Colpitts oscillator is determined by a series resonant Circuit
- ii The frequency of a Clapp-Gouriet oscillator is determined by a series resonant circuit

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 :- 3 The Colpitts oscillator uses a parallel resonant circuit. The Clapp-Gouriet oscillator uses a series resonant circuit.
