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.

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.


How does a Colpitts oscillator work?

A Colpitts oscillator is the electrical dual of a Hartley oscillator. In the Colpitts circuit, two capacitors and one inductor determine the frequency of oscillation. The feedback needed for oscillation is taken from a voltage divider made by the two capacitors, where in the Hartley circuit the feedback is taken from a voltage divider made by two inductors (or a tapped single inductor). (Note: the capacitor can be a variable device by using a varactor). Oscillation frequency The ideal frequency of oscillation for the circuit is given by the equation: where the series combination of C1 and C2 creates the effective capacitance of the LC tank. Real circuits will oscillate at a slightly lower frequency due to junction capacitances of the transistor and possibly other stray capacitances


Application of flip flop as a frequency doubler?

One way of using a flip flop as a frequency doubler is to create an oscillator at the desired doubled frequency, and then divide by two with the flip flop, resulting in the original frequency, and then controlling the oscillator with a phase locked loop.

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 advantages of oscillator?

clapp oscillator have frequency more stable and accurate than colpitts oscillator.

How is colpitts oscillator better than hartley oscillator?

No because hartley uses inductors which are bulky and economically not feasible to obtain tuning inductors as compared to colpitt's which uses capacitors which are relatively very cheap and small.

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.
