Lett.", year="1978", volume="33", number="2", pages="151--154", optkeywords="Schottky", abstract="Frequency countings close to a phase locked zone in an electronic receiver show a 1/f power spectral density. The noise scaling versus the frequency deviation and the open loop gain are found from Adler{\textquoteright}s model of the phase locked loop. This fully agrees with experiments performed at 5 MHz on a receiver with a Schottky diode mixer and a low pass filter. The 1/f amplitude and frequency noise due to the whole set of (sub)harmonics is explained from a nonlinear mapping, with a coupling coefficient related to the structure of prime numbers.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=587), last updated on Wed, 02 Dec 2009 15:30:09 -0600" }
