To calculate the frequency of the RC phase shift oscillator & to measure the phase angles at different RC sections. Application:- -This phase shift oscillator is used to generate the signals over an extensive range of frequency. They used in musical instruments, GPS units, & voice synthesis. -The applications of this phase shift oscillator include voice synthesis, musical instruments, and GPS units. Advantages of RC Phase Shift Oscillator The advantages of this phase shift oscillator include the following. The oscillator circuit designing is easy with basic components like resistors as well as capacitors. This circuit is not expensive and gives excellent frequency stability. These are mainly suitable for low-frequencies This circuit is simpler compared with a Wein bridge oscillator because it doesn’t require the stabilization planning & negative feedback. The circuit output is sinusoidal that is somewhat distortion free. The frequency range of this circuit will range from a few Hz to hundreds of kHz Disadvantages of RC-Phase Shift Oscillator The disadvantages of this phase shift oscillator include the following. The output of this circuit is small because of the smaller feedback It requires 12 volts battery for developing a suitably huge feedback voltage. It is hard for this circuit to create oscillations because of the small feedback The frequency stability of this circuit is not good to compare with Wien bridge oscillator.
