Phase shift oscillator

  1. Nov 26, 2009 #1
    hi
    i want to know why R-C oscillator is called phase shift oscillator? does it only shift the phase?How the amplitude and the frequency of oscillator ca be changed?
    thanks

    Welcome to the PF. Could you please give more details about what you mean by an RC Oscillator? An RC all by itself won't make an oscillation, right? What else goes into an RC Oscillator? And what can you tell us about the definition of phase shift? What is it? Phase of what compared to what?

    an oscillator having resistor and capacitor may be called an R-C oscillator.

    phase shift means shifting the phase inversely by 180 degree.The phase of output signal compared to input signal.
