A generator is used to convert mechanical energy to electrical energy.
An oscillator is used to convert dc to ac
clapp oscillator have frequency more stable and accurate than 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.

The amplifier projects the audio signal into something we can comprehend. The oscillator creates a fixed or variable pitch, which is fed to the amplifier. Amplifiers are circuits which transfer an input signal into an output signal. Oscillators are autonomous circuits powered by a constant energy source. They produce a steady state signal e.g. a sinusoidal signal or a chaotic signal.
depends on the oscillator and its purpose
Colpitt oscillator is better than hartley because colpitt produces less phase noise and uses capacitor instead of inductor as used in hartley oscillator which means that area is also saved.
oscillator frequency is different.crystal working piezo electric effect
difference between local oscillator and controlled oscillator
The difference between an RC and LC is that the frequency - determining device in the RC oscillator is not a tank circuit. LC can operate with A or C biasing, while RC can only operate with A.
the fundamental difference between a battery and a generator is that a battery uses chemicals
location of local oscillatorself - oscillator is integral to mixerseparate - oscillator is a physically separate stage
Rc phase shift uses negative feedback.. Weinbridge uses both +ve and -ve feedback
colpitts oscillator has two coils in series and one capacitor in parallel. hartley oscillator has one capacitor and one coil in parallel
it is
It can be used as a Sawtooth wave generator
The difference between a commercial power generator and a regular power generator is that a commercial one is much expensive than the regular one. It's much better to purchase the regular generator if your not planning to use it for business purposes.
In case of HARMONIC OSCILLATOR the relation b/n FORCE AND DISPLACEMENT is LINEAR but in the case of ANHARMONIC OSCILLATOR relation b/n force and displacement is not linear.Hence this non-linearity arises the fact that the spring is not capable of exerting a restoring force that is proportional to the displacement.
magneto is dc
