This is a book for engineers concerned with jitter: the e ects of noise visible in the time domain. The material presented will be helpful for work at both the system level and the circuit level: At the system level, the challenge is to describe, specify, and measure time domain uncertainty and when necessary, relate jitter to phase noise speci cations in the frequency domain. At the circuit level, the challenge is to design low noise circuitry within power, area, and process constraints so that ultimate performance meets system level requirements. Throughout the book concepts are presented in the context of an - gineering application requiring low jitter performance: the voltage controlled oscillator (VCO) used in a phase-locked loop (PLL). Techniques are presented for circuit-level design of low jitter delay elements for use in ring oscillators, as well as relating the circuit-level characteristics to system-level performance. Although the emphasis is on time-domain (jitter) measures of oscillator p- formance, a simple method of translating performance to frequency domain (phase noise) measures is presented as well. Structure of this Book This book is divided into nine chapters. The diagram on the following page shows the relationship between material in each chapter as well as placement in the system-level vs. circuit-level design hierarchy. Wherever possible, - perimental veri cation is presented in the same chapter as the corresponding theoretical development, rather than being isolated in a separate chapter.
From Azzedine AlaÃ¯a, CristÃ³bal Balenciaga, and Coco Chanel, to Alexander McQueen, Yves Saint Laurent, and Vivienne Westwood, a centuryâ€™s worth of fashion greats from the permanent collection of The Museum at the Fashion Institute of Technology are celebrated in this limited-edition volume. Photographs of over 500 garments selected from the Museumâ€™s permanent collection illuminate each of the featured designers, while texts by the curators explain why each designer is important in fashion history and what is special about the individual pieces featured.
AutoCAD is the industry standard for two-dimensional construction drawings, and this manual was created specifically to help designers master it. Neither overly simplistic nor excessively technical,Digital Drawing for Designers: A Visual Guide to AutoCAD 2012 teaches by relating to what architects and interior designers understand best: the visual world. Beginning with the building blocks of drawing (lines, circles, and arcs), the book progresses through architectural graphic standards, enabling students to create drawings that effectively communicate their design ideas. Advanced features such as annotative dimensions, annotative blocks, express tools, and linking drawings (XREFs) are also covered. Instructions are illustrated using language and concepts from manual drafting, facilitating a smooth transition to the digital environment for all designers. New learners will appreciate the step-by-step lessons and visual illustrations, while experienced design professionals can easily access material to refresh their knowledge. Clear, concise, and above all visual, this AutoCAD guide speaks directly to the needs of architects and interior designers.
