A: desirable oscillator will have no frequency deviation as a function of external influences such as temperature and more. Stability is measured as a % factor considering outside interferences
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
Practically, there are some factors that affect the frequency stability of Variation in temperature Oscillator • Circuit Components- Values of R, L and C changes with temperature• Transistor...
