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 else can I help you with?
What is the difference between LC and RC filters?
LC means coil capacitance circuit RC means resistance capacitance circuit
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
What is the difference between transformer coupling and RC coupling?
RC COUPLING :- is the most Commonly used Coupling Between the two stages of a cascaded or multistage amplifier because it is cheaper in cost and Very compact circuit and provides excellent frequency response. TRANSFORMER COUPLING :- Impedence Coupling results in more efficient amplification because no signal power is wasted in Inductor L. Such Coupling has the drawback of being larger, Heavier and Costlier than the RC COUPLING. Impedence Coupling is rarely used beyond audio range . by : Muhammad zubair.... muet student of telecom.
Is it true if supply voltage is increased the capacitance of a RC circuit will decrease?
No. Capacitance is determined by the area of overlap of its plates, the distance between them, and the absolute permittivity of its dielectric.
How can a tuned RC circuit improve the power factor of an inductive motor circuit?
The RC circuit can reduce the phase shift between the voltage and current in the power line. The phase shift is caused by the inductance of the motor. The phase shift between the voltage and current in the power line causes problems due to the presence of so called imaginary current or power that does no work but must be supplied by the power source.
Classification of oscillators?
Phase-shift oscillator Armstrong oscillator Cross-coupled LC oscillator RC oscillator
What is type of oscillations?
Phase-shift oscillator Armstrong oscillator Cross-coupled LC oscillator RC oscillator
What is the difference between LC and RC filters?
LC means coil capacitance circuit RC means resistance capacitance circuit
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.
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 is the basic difference between relaxation oscillator and RC 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 are the advantages of wien bridge oscillator?
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network
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 RC phase shift oscillator more stable than a crystal oscillator or not?
no
What is the difference between oscillator and multivibrators?
Oscillator is an electronic circuit which can generate oscillating sin signal without any oscillating input with use of positive feedback Multivibrator is a two stage RC coupled amplifier circuit which can generate squae signal without ac input
What is name the form RC networks?
The name for an RC network is an oscillator.
Which is better RC phase shift oscillator or wien bridge oscillator?
phaseshift of wienbridge is 0
