PSpice for Filters and Transmission Lines (Paperback)

In this book, PSpice for Filters and Transmission Lines, we examine a range of active and passive filters where each design is simulated using the latest Cadence Orcad V10.5 PSpice capture software. These filters cannot match the very high order digital signal processing (DSP) filters considered in PSpice for Digital Signal Processing, but nevertheless these filters have many uses. The active filters considered were designed using Butterworth and Chebychev approximation loss functions rather than using the ‘cookbook approach’ so that the final design will meet a given specification in an exacting manner. Switched-capacitor filter circuits are examined and here we see how useful PSpice/Probe is in demonstrating how these filters, filter, as it were. Two-port networks are discussed as an introduction to transmission lines and, using a series of problems, we demonstrate quarter-wave and single-stub matching. The concept of time domain reflectrometry as a fault location tool on transmission lines is then examined. In the last chapter we discuss the technique of importing and exporting speech signals into a PSpice schematic using a tailored-made program Wav2ascii. This is a novel technique that greatly extends the simulation boundaries of PSpice. Various digital circuits are also examined at the end of this chapter to demonstrate the use of the bus structure and other techniques.

在這本書《PSpice濾波器和傳輸線》，我們使用最新的Cadence Orcad V10.5 PSpice捕獲軟體模擬了一系列主動和被動濾波器的設計。這些濾波器無法與《PSpice數字信號處理》中考慮的非常高階的數字信號處理（DSP）濾波器相媲美，但這些濾波器仍然有很多用途。所考慮的主動濾波器是使用Butterworth和Chebychev逼近損失函數設計的，而不是使用“食譜方法”，以便最終設計能夠以精確的方式滿足給定的規格。我們還研究了開關電容濾波電路，並展示了PSpice/Probe在演示這些濾波器的過程中的實用性。我們討論了雙端口網絡作為傳輸線的介紹，並通過一系列問題演示了四分之一波和單阻抗匹配。然後，我們研究了時域反射測量作為傳輸線上的故障定位工具。在最後一章中，我們討論了使用定制程序Wav2ascii將語音信號導入和導出PSpice原理圖的技術。這是一種新穎的技術，大大擴展了PSpice的模擬範圍。本章末尾還研究了各種數字電路，以演示匯流排結構和其他技術的使用。
