What are the frequency determining components in a phase shift oscillator?
The frequency determining components in a phase shift oscillator are the series of resistive/capacitive filters on the output of the inverting amplifier. See accompanying link.
How phase shift oscillator introduces phase shaft of 180 degree?
You mean "how does a phase shift oscillator introduce a phase shift of 180 degrees?" OK, we need two things for this type of oscillator: 1. A loop gain of more than 1.0, 2. A loop phase shift of zero degrees. The PSO achieves the gain using a valve, transistor, or op amp. It achieves the loop phase shift using (i) an inverting amplifier, equal to a phase shift of 180º, plus (ii) a network (usually resistor-capacitor) with a further phase shift of 180º. The loop shift is thus (180+180) = 360º/ zero degrees. It's easiest to use a three-part phase shift network, as the theoretically-possible two-part is difficult to make work, and the four-part is unneccessarily complex. The required phase shift of exactly 180º occurs at only one frequency, determined by the values of R and C.
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
Viva questions for RC phase shift oscillator?
A phase-shift oscillator is a simple electronic oscillator circuit. It consists of an inverting amplifier element such as a transistor or op amp, with its output fed back into its input through an filterconsisting of a network of resistors and capacitors. The feddback network 'shifts' the phase of the amplifier output by 180 degrees at the oscillation frequency, to give positive feedback.[1] Phase shift oscillators are mostly used at lower frequencies, often in the audio frequency range as audio oscillators.
How do you design phase shift oscillator circuit with amplitude stabilization?
you ask professor smith from the UNH ECE department
How does the phase-shift oscillator get its name?
Phase shift oscillator consists
Why is the R-C oscillator also called a phase shift oscillator?
The R-C oscillator is also called a phase shift oscillator because the R-C filter creates a phase shift from input to output. The feedback portion of the oscillator (an amplifier) then serves to pump energy back into the filter.
How would you explain phase shift oscilater?
A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output.

How to design a phase shifter circuit using operational amplifier to have a desired phase shift?
There are many phase shift oscillator circuits on the internet. Google search, `phase+shift+oscillator+schematics` and `phase+shift+oscillator+diagrams`. Generally, if you want to change the phase shift characteristics, you'll need to substitute some fixed resistors with variable resistors and depending where they're placed, you can either change the operating frequency or the waveform characteristics.
Which is better RC phase shift oscillator or wien bridge oscillator?
phaseshift of wienbridge is 0
What is the difference between wien-bridge oscillator and phase-shift oscillator?
Rc phase shift uses negative feedback.. Weinbridge uses both +ve and -ve feedback

Why only 60 degrees phase shift in RC phase shift oscillator?
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.
Why do you use three R-C section in an RC phase shift oscillator?
To obtain a phase-shift of 180 degree.
