What is role of LC circuit in the hartley oscillator?
Self-tuning feedback
What are the essential components of a feedback LC oscillator?
The essential components of a feedback LC oscillator include an inductor (L) and a capacitor (C) connected in a feedback loop, a gain element such as a transistor or amplifier to compensate for energy losses, and a feedback network to sustain oscillations by providing positive feedback. The LC tank circuit stores and exchanges energy between the inductor and capacitor to generate an oscillating signal at the resonant frequency of the tank circuit.
Differetiate between LC oscillators and crystal controlled oscillators?
LC oscillators use inductors and capacitors to generate a frequency, while crystal controlled oscillators use a quartz crystal to establish the frequency. LC oscillators can be less stable and accurate compared to crystal controlled oscillators, which offer better precision and stability. Crystal controlled oscillators are commonly used in applications where precise frequency control is essential.
What is Franklin oscillator?
It is an electrical oscillator which uses two transistors or vacuum tubes and a LC circuit. The two transistors are connected as a two stage amplifier, both stages are inverting. the output of the second is coupled to the input of the first by a tuned circuit. Provided the amplifiers have enough gain, the circuit will oscillate, because the two amplifiers each give 180 degree phase shift, so the output is in phase iwth the input, so the oscillations build, until they are limited in amplitude by gain compression.
How does an oscillator work?
An oscillator works in different ways in different electronic equipment. For example, there is a quartz oscillator in a quartz watch that can keep track of the time. A pendulum of a clock is an oscillator that goes back and forth using potential and kinetic energy.
Classification of oscillators?
Phase-shift oscillator Armstrong oscillator Cross-coupled LC oscillator RC oscillator
What is a frequency range of LC oscillator?
depends on the oscillator and its purpose
What are the Difference between RC oscillator And LC oscillator?
The difference between an RC and LC is that the frequency - determining device in the RC oscillator is not a tank circuit. LC can operate with A or C biasing, while RC can only operate with A.

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.

State four types of LC oscillators?
Four types of LC oscillators include voltage controlled oscillators, drift control oscillators, crystal oscillators, and tuned circuit oscillators. A tuned circuit oscillator is the most common type of oscillator.
What is a local oscillation?
A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)

Why LC oscillator not suitable for audio frequency?
Another type of sine-wave generator uses inductors and capacitors for its frequency-determining network. This type is known as the LC OSCILLATOR. LC oscillators, which use tank circuits, are commonly used for the higher radio frequencies. They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
