What else can I help you with?
What are the advantages of clap oscillator?
clapp oscillator have frequency more stable and accurate than colpitts oscillator.
What is a frequency range of LC oscillator?
depends on the oscillator and its purpose
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 the use of reflex klystron oscillator?
radar transmitters UHF TV transmission
Why is a crystal oscillator required in a radio transmitter?
SOME kind of oscillator is required, to create the AC signal that will be modulated, amplified, and eventually sent up to the antenna to be transmitted. It doesn't have to be a crystal oscillator, though.
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?

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
What the major components of a colpitts oscillator?
1.CE amplifier circuit 2.LC oscillator circuit
What type of transistor used in colpitts oscillator?
whatever works at the desired operating frequency
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.
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.
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
