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 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
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.
Classification of oscillators?
Phase-shift oscillator Armstrong oscillator Cross-coupled LC oscillator RC oscillator
What are the methods of changing the frequency of Wien Bridge Oscillator?
f=0.159/RC . where R and C are the feedback network of wien bridge
What is type of oscillations?
Phase-shift oscillator Armstrong oscillator Cross-coupled LC oscillator RC oscillator
What are the advantages and disadvantages of RC phase shift oscillator?
Advantages: it improves frequency stability. phase modulation n demodulation is easy as compared to frequency modulation.
Is RC phase shift oscillator more stable than a crystal oscillator or not?
no
Application of wein bridge oscillator?
A Wein bridge oscillator is commonly used in electronic circuit design to generate low frequency sine waves. It is often utilized in audio applications, such as in tone generators and audio oscillators, as well as in low frequency signal processing circuits. Additionally, it can be employed in frequency synthesizers and function generators.
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 is an RC oscillator?
AnswerOscillator that uses two passive elements for the timing. Namely resistor and capacitor.AnswerIt's an oscillator whose frequency-determining "tank" does not contain an inductive element, like a coil. These are good for extremely low frequencies--down to a few Hertz--but LC oscillators are better at radio frequencies.AnswerAn Rc oscillator is an oscillator that uses 3 or more phase shift networks, ( a network of a capacitor and resistor) as a frequency determining network (tank circuit) and a transistor to amplify that output, that only allows a certain frequency through by only letting the frequency that is able to shift 180 degrees out of phase through. And also has a feedback network from the collector (of the transistor) circuit, to compensate for circuit loss to oscillation.
