The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented. The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940). The design is fully pipelined for maximum throughput.

MATSNL is a package of MATLAB M-files for computing wireless sensor node lifetime/power budget and solving optimal node architecture choice problems. It is intended as an analysis and simulation tool for researchers and educators that are easy to use and modify. MATSNL is designed to give the rough power/ lifetime predictions based on node and application specifications while giving useful insight on platform design for the large node lifetime by providing side-by-side comparison across various platforms. The MATSNL code and manual can be found at the bottom of this page. A related list of publications describing the models used in MATSNL is posted on the ENALAB part of the 2 project at http://www.eng.yale.edu/enalab/aspire.htm

本代碼為編碼開(kāi)關(guān)代碼，編碼開(kāi)關(guān)也就是數(shù)字音響中的 360度旋轉(zhuǎn)的數(shù)字音量以及顯示器上用的（單鍵飛梭開(kāi) 關(guān)）等類似鼠標(biāo)滾輪的手動(dòng)計(jì)數(shù)輸入設(shè)備。 我使用的編碼開(kāi)關(guān)為5個(gè)引腳的，其中2個(gè)引腳為按下 轉(zhuǎn)輪開(kāi)關(guān)（也就相當(dāng)于鼠標(biāo)中鍵）。另外3個(gè)引腳用來(lái) 檢測(cè)旋轉(zhuǎn)方向以及旋轉(zhuǎn)步數(shù)的檢測(cè)端。引腳分別為a,b,c b接地a，c分別接到P2.0和P2.1口并分別接兩個(gè)10K上拉 電阻，并且a，c需要分別對(duì)地接一個(gè)104的電容，否則 因?yàn)榫幋a開(kāi)關(guān)的觸點(diǎn)抖動(dòng)會(huì)引起輕微誤動(dòng)作。本程序不 使用定時(shí)器，不占用中斷，不使用延時(shí)代碼，并對(duì)每個(gè) 細(xì)分步數(shù)進(jìn)行判斷，避免一切誤動(dòng)作，性能超級(jí)穩(wěn)定。 我使用的編碼器是APLS的EC11B可以參照附件的時(shí)序圖 編碼器控制流水燈最能說(shuō)明問(wèn)題，下面是以一段流水 燈來(lái)演示。

JavaServer Faces (JSF) is the “offcial” component-based view technology in the Java EE web tier. JSF includes a set of predefned UI components, an event-driven programming model, and the ability to add third-party components. JSF is designed to be extensible, easy to use, and toolable. This refcard describes the JSF development process, standard JSF tags, the JSF expression language, and the faces-confg.xml confguration fle.
