商品描述

This book is Volume II of the series DSP for MATLAB™ and LabVIEW™. This volume provides detailed coverage of discrete frequency transforms, including a brief overview of common frequency transforms, both discrete and continuous, followed by detailed treatments of the Discrete Time Fourier Transform (DTFT), the z -Transform (including definition and properties, the inverse z -transform, frequency response via z-transform, and alternate filter realization topologies (including Direct Form, Direct Form Transposed, Cascade Form, Parallel Form, and Lattice Form), and the Discrete Fourier Transform (DFT) (including Discrete Fourier Series, the DFT-IDFT pair, DFT of common signals, bin width, sampling duration and sample rate, the FFT, the Goertzel Algorithm, Linear, Periodic, and Circular convolution, DFT Leakage, and computation of the Inverse DFT). The entire series consists of four volumes that collectively cover basic digital signal processing in a practical and accessible manner, but which nonetheless include all essential foundation mathematics. As the series title implies, the scripts (of which there are more than 200) described in the text and supplied in code form (available via the internet at http://www.morganclaypool.com/page/isen) will run on both MATLAB™ and LabVIEW™. The text for all volumes contains many examples, and many useful computational scripts, augmented by demonstration scripts and LabVIEW™ Virtual Instruments (VIs) that can be run to illustrate various signal processing concepts graphically on the user's computer. Volume I consists of four chapters that collectively set forth a brief overview of the field of digital signal processing, useful signals and concepts (including convolution, recursion, difference equations, LTI systems, etc), conversion from the continuous to discrete domain and back (i.e., analog-to-digital and digital-to-analog conversion), aliasing, the Nyquist rate, normalized frequency, sample rate conversion and Mu-law compression, and signal processing principles including correlation, the correlation sequence, the Real DFT, correlation by convolution, matched filtering, simple FIR filters, and simple IIR filters. Chapter 4 of Volume I, in particular, provides an intuitive or "first principle" understanding of how digital filtering and frequency transforms work, preparing the reader for the present volume (Volume II). Volume III of the series covers digital filter design (FIR design using Windowing, Frequency Sampling, and Optimum Equiripple techniques, and Classical IIR design) and Volume IV, the culmination of the series, is an introductory treatment of LMS Adaptive Filtering and applications.

商品描述(中文翻譯)

本書是《DSP for MATLAB™ and LabVIEW™》系列的第二卷。本卷詳細介紹了離散頻率變換,包括常見的離散和連續頻率變換的簡要概述,接著詳細介紹了離散時間傅立葉變換(DTFT)、z-變換(包括定義和性質、逆z-變換、通過z-變換的頻率響應,以及替代濾波器實現拓撲結構(包括直接型、直接型轉置型、級聯型、並聯型和格子型))以及離散傅立葉變換(DFT)(包括離散傅立葉級數、DFT-IDFT對、常見信號的DFT、頻帶寬度、取樣持續時間和取樣率、快速傅立葉變換(FFT)、Goertzel算法、線性、周期性和循環卷積、DFT泄漏以及反向DFT的計算)。整個系列共有四卷,以實用和易於理解的方式全面介紹了基礎數字信號處理,但同時包含了所有必要的基礎數學知識。正如系列標題所示,文本中描述的腳本(超過200個)以代碼形式提供(可通過網址http://www.morganclaypool.com/page/isen 在網上獲取),可以在MATLAB™和LabVIEW™上運行。所有卷的文本都包含許多示例和有用的計算腳本,並附有演示腳本和LabVIEW™虛擬儀器(VIs),可以在用戶的計算機上以圖形方式演示各種信號處理概念。第一卷由四章組成,簡要概述了數字信號處理領域、有用的信號和概念(包括卷積、遞迴、差分方程、LTI系統等)、從連續域到離散域的轉換(即模擬到數字和數字到模擬轉換)、混疊、奈奎斯特率、標準化頻率、取樣率轉換和Mu-law壓縮,以及信號處理原理,包括相關性、相關性序列、實數DFT、通過卷積進行相關性、匹配濾波、簡單FIR濾波器和簡單IIR濾波器。特別是第一卷的第四章提供了對數字濾波和頻率變換的直觀或“第一原理”理解,為讀者準備了本卷(第二卷)。系列的第三卷涵蓋了數字濾波器設計(使用窗函數、頻率取樣和最佳等波紋技術的FIR設計,以及經典IIR設計),而系列的第四卷則是對LMS自適應濾波和應用的入門介紹。目錄:離散時間傅立葉變換/ z-變換/ DFT。
