For wireless communication engineers, it is important to have solid fundamental knowledge of noise and how to minimize it by stabilizing the incoming/outgoing waves. This introductory text of frequency stability offers discussion of the noise from the practical and theoretical points of view, proceeding with investigation of frequency and time fluctuations in resonators, and continue with stability of both of standard and practical microwave oscillators. Finally, the author discusses noise properties of building circuit blocks introducing a chapter on time domain properties and their...

Phase lock loop frequency synthesis finds uses in a myriad of wireless applications - from local oscillators for receivers and transmitters to high performance RF test equipment. As the security and reliability of mobile communication transmissions have gained importance, PLL and frequency synthesisers have become increasingly topical subjects.

Phase Lock Loops and Frequency Synthesis examines the various components that make up the phase lock loop design, including oscillators (crystal, voltage controlled), dividers and phase detectors. Interaction amongst the various components...

With the advent of integrated circuits (IC), digital systems have become widely used in modern electronic devices, including communications and measurement equipment. Direct Digital Frequency Synthesizers (DDS) are used in communications as transmitter exciters and local oscillators in receivers. The advantages are superior frequency stability, the same as that of the driving clock oscillator, and short switching times. The difficulties are lower output frequencies and rather large spurious signals.

Compiled for practicing engineers who do not have the prerequisite of a specialist's...
