Von der hinteren Coverseite

Electrical Engineering / Direct Digital Frequency Synthesizers

With the advent of integrated circuits, digital systems have become widely used in modern electronic devices, including communications and measurement equipment. Direct Digital Frequency Synthesizers (DDS or DDFS) are used in communications as transmitter exciters, phase modulators, and local oscillators in receivers. The advantages are small size, superior frequency stability (the same as that of the driving clock oscillator), and short switching times. The difficulties are lower RF output frequencies and rather large spurious signals. Compiled for engineers dealing with systems and practical applications, Direct Digital Frequency Synthesizers―a collection of 40 important reprinted papers and nine new contributions―presents a comprehensive introduction to DDS properties and a clear understanding of actual devices. The information in this volume can lead to easier computer simulations and improved designs. Featured topics include:

• Discussion of principles and state-of-the-art, wide-range DDS
• Investigation of spurious signals in DDS
• Combination of DDS with phase-lock loops
• Examination of phase and background noise in DDS
• Introduction to digital-to-analog conversion
• Analysis of mathematics of quasiperiodic omission of pulses
