Which oscillator circuit uses a tapped coil in the tuned circuit?
Several oscillator designs use a tapped coil in the tuned circuit. The most common is the Hartley 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.
How hartley oscillator produces a output waveform without input?
it uses the noise in air.
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.
How do you design hartley oscillator using transistor?
i will put tank ckt and give it to transistor via positive feedback
Is hartley oscillator is better than colpitt oscillator?
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.
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 the difference between colpitts and hartley ossilator?
colpitts oscillator has two coils in series and one capacitor in parallel. hartley oscillator has one capacitor and one coil in parallel

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.
Who invented high frequency oscillator?
Nikoli Tesla, Colpits or Hartley
What is role of LC circuit in the hartley oscillator?
Self-tuning feedback
What is meant by tank circuit in hartley oscillator?
it is the circuit that is responsible for producing oscillation.In hartley it is two inductors connected in series and a capacitor parallel to this series connection.Without tank oscillator tends to act as as an amplifier.
What are the disadvantages of hartley oscillator?
Disadvantages of Hartley Oscillators The output is rich in harmonic content and therefore not suitable where a pure sine wave is required.
How hartley oscillator produces a output waveform without input?
it uses the noise in air.
