When I started writing the first edition of RF Power Amplifiers for Wireless Communications,some time back in 1997, it seemed that I was roaming a largely uninhabitedlandscape. For reasons still not clear to me there were few, if any, otherbooks dedicated to the subject of RF power amplifiers. Right at the same time, however,hundreds of engineers were being assigned projects to design PAs for wirelesscommunications products. It was not, therefore, especially difficult to be successfulwith a book that was fortuitously at the right place and the right time.

針對嵌入式機器視覺系統(tǒng)向獨立化、智能化發(fā)展的要求，介紹了一種嵌入式視覺系統(tǒng)--智能相機。基于對智能相機體系結構、組成模塊和圖像采集、傳輸和處理技術的分析，對國內外的幾款智能相機進行比較。綜合技術發(fā)展現(xiàn)狀，提出基于FPGA+DSP模式的硬件平臺，并提出智能相機的發(fā)展方向。分析結果表明，該系統(tǒng)設計可以實現(xiàn)脫離PC運行，完成圖像獲取與分析，并作出相應輸出。 Abstract: This paper introduced an embedded vision system-intelligent camera ，which was for embedded machine vision systems to an independent and intelligent development requirements. Intelligent camera architecture， component modules and image acquisition， transmission and processing technology were analyzed. After comparing integrated technology development of several intelligent cameras at home and abroad， the paper proposed the hardware platform based on FPGA+DSP models and made clear direction of development of intelligent cameras. On the analysis of the design， the results indicate that the system can run from the PC independently to complete the image acquisition and analysis and give a corresponding output.

Jitter is extremely important in systems using PLL-based clock drivers. The effects of jitter range from not having any effect on system operation to rendering the system completely non-functional. This application note provides the reader with a clear understanding of jitter in high-speed systems. It introduces the reader to various kinds of jitter in high-speed systems, their causes and their effects, and methods of reducing jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.
