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.
no
The name for an RC network is an oscillator.
phaseshift of wienbridge is 0
The simplest application of a UJT is as a relaxation oscillator, which is defined as one in which a capacitor is charged gradually and then discharged rapidly.
In an RC phase shift oscillator, one emitter follower stage is typically used to provide the required phase shift. In a Wien bridge oscillator, two emitter followers are used to achieve the required feedback and oscillation.
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.
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.
to generate the sinusodal waveform(to generate sustained oscillations)
In order for an oscillator to be stable, its total phase shift must be 180 degrees. The most common design of an RC phase shift oscillator is three identical RC stages in series, which means that each stage contributes 60 degrees. For more information, please see the Related Link below.
