{"product_id":"9780792393092","title":"Sigma Delta Modulators","description":"Analog-to-digital (A\/D) converters are key components in  digital signal processing (DSP) systems and are therefore receiving  much attention as DSP becomes increasingly prevalent in telephony,  audio, video, consumer products, etc. The varying demands on  conversion rate, resolution and other characteristics have inspired a  large number of competing A\/D conversion techniques. Sigma Delta  Modulators: Nonlinear Decoding Algorithms and Stability  Analysis is concerned with the particular class of A\/D techniques  called oversampled noise-shaping (ONS) that has recently come into  prominence for a number of applications. The popularity of ONS  converters is due to their ease of implementation and robustness to  circuit imperfectors.  An ONS converter consists of an encoder that generates a high-rate,  low-resolution digital signal, and a decoder that produces a low-rate,  high-resolution digital approximation to the analog encoder input. The  conventional decoding approach is based on linear filtering.  Sigma Delta Modulators presents the optimal design of an  ONS decoder for a given encoder. It is shown that nonlinear decoding  can achieve gains in signaling ratio and the encoder architecture. The  book then addresses the instability problem that plagues higher-order  ONS encoders. A new stability concept is introduced that is  well-suited to ONS encoders, and it is applied to the double-loop  encoder as well as to the class of interpolative encoders. It is shown  that there exists a trade-off between stability and SNR performance.  Based on the results, explicit design examples are presented.  Sigma Delta Modulators: Nonlinear Decoding Algorithms and  Stability Analysis is a valuable reference source for  researchers and engineers in industry and academia working on or  interested in design and analysis of A\/D converters, particularly to  those working in quantization theory and signal reconstruction, and  can serve as a text for advanced courses on the subjects treated.","brand":"Soren Hein, Avideh Zakhor","offers":[{"title":"Default Title","offer_id":45858115060030,"sku":"9780792393092","price":4648.4,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4357\/7662\/products\/9780792393092_88db82f2-b93a-4b8c-8780-5b418873f424.jpg?v=1707327071","url":"https:\/\/exclusivebooks.co.za\/products\/9780792393092","provider":"Exclusive Books Online","version":"1.0","type":"link"}
