    Hi, all :)
    Just wonder if anyone happens to know what is the phase shifter. Does it just shift the phase of an input signal, or the frequency too? I am trying to build a circuit that consists of the phase shifter and crystal oscillator. Just dont know how it works to make the oscillator to oscillate at the resonance frequency. Any suggestion will be highly appreciated.
    Thank you.
