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 the difference between LC and RC filters?
LC means coil capacitance circuit RC means resistance capacitance circuit
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.
Time constant of LC circuit is?
T=sqrtLC
What is the roll of bleeder resistance in LC filter circuit and what will happen if the bleeder resistor is not used in circuit?
jgfkf
What the major components of a colpitts oscillator?
1.CE amplifier circuit 2.LC oscillator circuit

What is role of LC circuit in the hartley oscillator?
Self-tuning feedback
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)

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 is type of oscillations?
Phase-shift oscillator Armstrong oscillator Cross-coupled LC oscillator RC oscillator
How you can make a oscillator without using LC?
don't use LC
Why RC oscillators are not suitable for high frequency generation?
Because an RC oscillator is affected by stray capacitance in the active components in the circuit. HF oscillators use an LC tuned circuit to define the frequency.
What are disadvantage of lc oscillator over the RC oscillator?
DISADVANTAGES OF RC PHASE SHIFT OSCILLATOR.1. The output is small due to smaller feedback. 2. It is difficult for the Circuit to start oscillations.3. The Frequency stability is not so Good.4. It requires high Vcc. For large feedback.
