Stability of the oscillator means the how much frequency stability it have. Measure of frequency stability comes from "rate of change of phase w.r.t frequency", the more it is the more stable the oscillator is, because we know that one condition for oscillation is that the loop gain phase shift should be zero, hence if due to ckt. parameters there is some change in phase then by very little variations in frequency we can bring back the loop gain phase shift to zero. ex. is LC tank circuit which act as an osciilator at resonant frequency. Frequency stability can also be measure from quality factor, the higher it is the more stable ckt. is,

What are the advantages of wien bridge oscillator?
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network
What are the advantages of clap oscillator?
clapp oscillator have frequency more stable and accurate than colpitts oscillator.
What is a Colpitts oscillator?
A Colpitts oscillator is the electrical dual of a Hartley oscillator. The Hartley oscillator is an LC electronic oscillator that derives its feedback from a tapped coil in parallel with a capacitor. http://en.wikipedia.org/wiki/Colpitts_oscillator http://en.wikipedia.org/wiki/Hartley_oscillator ~MECHASUN~ A Colpitts oscillator is the electrical dual of a Hartley oscillator.

What is a frequency range of LC oscillator?
depends on the oscillator and its purpose
How crystal oscillator provides good frequency stability?
A: It is a mechanical device once it is exited it will oscillate at its mechanical frequency unless the mechanics changes it will not drift as compered to other oscillators
What is the difference between colpitts and clapp oscillator?
The Clapp oscillator is a variation of the Colpitts oscillator that includes an additional capacitor in series with the inductor to improve frequency stability. This additional capacitor in the Clapp oscillator helps reduce the effect of the active device's parasitic capacitance, leading to better frequency stability compared to the Colpitts oscillator.
What are the Factors affecting the frequency stability of an oscillator?
Factors affecting the frequency stability of an oscillator include temperature variations, voltage fluctuations, component aging, mechanical vibrations, and electromagnetic interference. These factors can cause deviations in the output frequency of the oscillator, impacting its stability over time. Using high-quality components, proper shielding, and temperature compensation techniques can help improve the frequency stability of an oscillator.
