What are the advantages of crystal oscillator?
A: When exited a crystal will oscillate at precise frequency due to its mechanical make up. An electronic oscillator external influences can make it to shift frequency very easily
Applications of wien bridge oscillator?
A Wein Bridge Oscillator is a oscillator which is used for the measurement of Audio Frequency.
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
Working of transistor as an oscillator?
A transistor is often referred to as an oscillator because of its ability to transfer resistance. it can also switch off and on repeatedly, mimicking an oscillator.
What is the advantages of L-C oscillator circuit?
At high frequencies for rc oscillators stray capacitances comes into act so q value reduses where for lc circutes q value is high
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 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?
Some disadvantages of Hartley oscillator include lower frequency stability compared to other oscillator configurations, sensitivity to variations in component values and external factors, and the potential for higher harmonic content in the output signal. Additionally, the design and tuning of a Hartley oscillator can be more complex compared to simpler oscillator configurations.
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
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 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.
What are the advantages of oscillator?
clapp oscillator have frequency more stable and accurate than colpitts oscillator.
What are the advantages of clap oscillator?
clapp oscillator have frequency more stable and accurate than colpitts oscillator.
How hartley oscillator produces a output waveform without input?
it uses the noise in air.
What is role of LC circuit in the hartley oscillator?
Self-tuning feedback
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.
