The goal is to present optimized filter architectures with regard to an efficient VLSI implementation. A fifth-order 1-bit sigma-delta modulator using local feedback techniques will be considered as the front-end A\/D converter. The subsequent digital filter reduces the sampling rate by a factor of 32. The decimation filter must guarantee a narrow transition band between 0.5 and 0.55 and stopband attenuation of 100dB.\u003cbr\u003eChapter 1 provides a brief introduction into the principles of digital signal processing. The considerations are focused on FIR filters due to the requirements for acoustic applications.\u003cbr\u003eChapter 2 illustrates the proposed overall structure and the design flow.\u003cbr\u003eThe objective of chapter 3 is to present the principles of oversampling data converters using sigma-delta techniques. The 5V fifth-order SD-modulator with 90dB dynamic range (SNR+THD) will be presented, which has been fabricated in 1.2µm CMOS technology. For the sake of simplicity and robustness, a 1-bit quantizer will be used.\u003cbr\u003eChapter 4 deals with typical hardware realizations of digital filters. Apart from the “brute force“ implementation of the multirate filter with identical filters running in parallel, also the LUT-based approach for small filter orders will be presented. Due to the advantages of compact implementation, the bit-serial approach and the bit-serial multiplier are investigated in detail.\u003cbr\u003eIn chapter 5 the straightforward one-stage multirate FIR filter will be introduced. To satisfy the specifications, a 4096 tap lowpass FIR filter will be designed. The influence of coefficient quantization is investigated and furthermore the “block scaling“ method, to repr","brand":"Child's World, Incorporated, The","offers":[{"title":"Default Title","offer_id":47059308970224,"sku":"9781503828223","price":31.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781503828223_p0.jpg?v=1763709182","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781503828223","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
