Best Answer

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.

Which part of the hartely oscillator decides frequency of oscillations?

An oscillator has a tuned circuit (inductance+capacitance) to determine the frequency. When the inductor is tapped to give the required phase-shift for oscillation it is a Hartley oscillator. When the capacitance is tapped it is a Colpitts.


What are the advantages of a Hartley oscillator?

advantages over what? Colpitts? Mostly the fact that it does not require a choke. A Hartley is more harmonic-rich than a Colpitts, so the main reason it is used lies in its (relative) ease of construction.


What is the Application of a Colpitts oscillator?

for radio frequnency ... and audio frequency. I have a Colpitts oscillator on a small piece of Veroboard 3/4"x 1/2"mounted on the terminals of a standard telephone earpiece. It uses the earpiece itslef as the inductor. The nominal impedance of the earpiece is about 300 ohms. With capacitors of 1μF and 0.47μF it oscillates at about 2kHz.
