Question

Which of these is incorrect for a Wien Bridge oscillator?

(a) Low distortion

(b) Good stability at the resonant frequency

(c) Difficult to tune

(d) Based on frequency selective form of a Wheatstone bridge

I got this question in an interview for internship.

I need to ask this question from Weinbridge Oscillator in chapter Oscillators of Analog Circuits

Answer 1

Right answer is (c) Difficult to tune

Easiest explanation: A Wien Bridge oscillator is a two-stage RC coupled amplifier circuit that has good stability at the resonant frequency. It has low distortion and is easy to tune. It is called so because the circuit is based on a frequency-selective form of the Wheatstone bridge.
