The effect of AM noise on correlation phase noise measurements [PDF]
, 2006 We analyze the phase-noise measurement methods in which correlation and averaging is used to reject the background noise of the instrument. All the known methods make use of a mixer, used either as a saturated phase detector or as a linear synchronous ...
