the Q factor could be derived from the modulation bandwidth of an 
oscillator [ the "old way" of measuring the Q of resonator of the 
running oscillator's ], therefore if we look the fluctuation spectrum of 
the frequency of an oscillator we could determine the Q. Any circular 
movement could be seen as the source of a harmonic oscillation.
