This texts contemporary approach focuses on the concepts of linear control systems, rather than computational mechanics. Straightforward coverage includes an integrated treatment of both classical and modern control system methods. The text emphasizes design with discussions of problem formulation, design criteria, physical constraints, several design methods, and implementation of compensators.Discussions of topics not found in other texts--such as pole placement, model matching and robust tracking--add to the texts cutting-edge presentation. Students will appreciate the applications and discussions of practical aspects, including the leading problem in developing block diagrams, noise, disturbances, and plant perturbations. State feedback and state estimators are designed using state variable equations and transfer functions, offering a comparison of the two approaches. The incorporation of MATLAB throughout the text helps students to avoid time-consuming computation and concentrate on control system design and analysis

This demo shows the BER performance of linear, decision feedback (DFE), and maximum likelihood sequence estimation (MLSE) equalizers when operating in a static channel with a deep null. The MLSE equalizer is invoked first with perfect channel knowledge, then with an imperfect, although straightforward, channel estimation algorithm. The BER results are determined through Monte Carlo simulation. The demo shows how to use these equalizers seamlessly across multiple blocks of data, where equalizer state must be maintained between data blocks.

If you d like to know where visitors to your site live, add this to your feedback forms. They just choose a region, and the second menu changes appropriately, allowing them to choose their country. (If they choose USA, it allows them to select their state) Neat!

Two scripts are included here. 1. convsys.m - combines the state space representation of two systems connected in series. [Ao,Bo,Co,Do]=convsys(A1,B1,C1,D1,A2,B2,C2,D2) This algorithm gives the convolution of two state space representations | A1 B1 | | A2 B2 | u ==> | | ==> | | ==> y | C1 D1 | | C2 D2 | The algorithm also accepts state space objects as inputs and gives out a state space object as output. 2. sysfeedbk.m [Ao,Bo,Co,Do]=convsys(A1,B1,C1,D1,A2,B2,C2,D2) Gives the closed loop state space representation for two systems connected with negative feedback in the following manner. | A1 B1 | u ==> | | ==> y + o | C1 D1 | | - | | | | A2 B2 | | |= | |= | | C2 D2 | The zip file also contains checkcompatibility.m , which checks the compatibility of matrix dimensions in the system and cleanss.m which can be used to clean a state space representation.

本文論述了狀態機的verilog編碼風格,以及不同編碼風格的優缺點，Steve Golson's 1994 paper, "State Machine Design Techniques for Verilog and VHDL" [1], is agreat paper on state machine design using Verilog, VHDL and Synopsys tools. Steve's paper alsooffers in-depth background concerning the origin of specific state machine types.This paper, "State Machine Coding Styles for Synthesis," details additional insights into statemachine design including coding style approaches and a few additional tricks.

One of the strengths of Synplify is the Finite State Machine compiler. This is a powerfulfeature that not only has the ability to automatically detect state machines in the sourcecode, and implement them with either sequential, gray, or one-hot encoding. But alsoperform a reachability analysis to determine all the states that could possibly bereached, and optimize away all states and transition logic that can not be reached.Thus, producing a highly optimal final implementation of the state machine.

Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal operating condition.

本文將接續介紹電源與功率電路基板，以及數字電路基板導線設計。寬帶與高頻電路基板導線設計a.輸入阻抗1MHz，平滑性(flatness)50MHz 的OP增幅器電路基板圖26 是由FET 輸入的高速OP 增幅器OPA656 構成的高輸入阻抗OP 增幅電路，它的gain取決于R1、R2，本電路圖的電路定數為2 倍。此外為改善平滑性特別追加設置可以加大噪訊gain，抑制gain-頻率特性高頻領域時峰值的R3。圖26 高輸入阻抗的寬帶OP增幅電路圖27 是高輸入阻抗OP 增幅器的電路基板圖案。降低高速OP 增幅器反相輸入端子與接地之間的浮游容量非常重要，所以本電路的浮游容量設計目標低于0.5pF。如果上述部位附著大浮游容量的話，會成為高頻領域的頻率特性產生峰值的原因，嚴重時頻率甚至會因為feedback 阻抗與浮游容量，造成feedback 信號的位相延遲，最后導致頻率特性產生波動現象。此外高輸入阻抗OP 增幅器輸入部位的浮游容量也逐漸成為問題，圖27 的電路基板圖案的非反相輸入端子部位無full ground設計，如果有外部噪訊干擾之虞時，接地可設計成網格狀(mesh)。圖28 是根據圖26 制成的OP 增幅器Gain－頻率特性測試結果，由圖可知即使接近50MHz頻率特性非常平滑，-3dB cutoff頻率大約是133MHz。
