Answer 1

Wein bridge oscillator:

The circuit diagram of the Wein bridge oscillator is shown below:

F2 U.B Madhu 28.12.19 D 2

The frequency of oscillation is given by:

\({\omega _o} = \frac{1}{{RC}}\)

\({f_o} = \frac{{1}}{{2\pi RC}}\)

Type of Oscillator	Approximate frequency range
Crystal oscillator	Fixed frequency
Tickler feedback oscillator	Nearly fixed frequency
Wien bridge oscillator	1 Hz to 1 MHz
Phase-shift oscillator	1 Hz to 10 MHz
Hartley's oscillator	10 kHz to 100 MHz
Colpitt's oscillator	10 kHz to 100 MHz
