Phase noise in signal sources /Theory and applications/
Abstract
A review of modulation theory is presented, taking into account amplitude modulation, phase modulation, frequency modulation, the addition of an arbitrary phase angle, linear approximation, phasor representation, the concept of conformability, and coherent demodulation of conformable signals. The relationship between phase jitter and noise density is considered along with noise induced frequency modulation, noise in oscillators, frequency multiplier chains, the use of phase lock loops, frequency synthesizers, the reciprocal relationships between phase noise and frequency stability (frequency domain to time domain transformations and their inverses, and system phase noise requirements. Subjects provided in an appendix include a summary of important formulae, a noise temperature and noise figure review, the quadrature representation of narrow band noise, the Q of varactor tuned oscillators, and the phase noise performance of Gunn oscillators.
