多媒體5.1聲道遙控功放全套方案(原理圖+制作元件參數全套)各功能描述: 1. 當A為低電平時,AC-3燈點亮,即是AC-3的輸入方式 當A為高電平時,STEREO燈點亮,即是STEREO的輸入方式 2. 當STANDBY燈點亮時，為待機狀態；此LED閃動時為MUTE狀態,PT2258為靜音狀態,同時STANDBY為低電平 3. 各聲道（FRONT，SUB，REAR，CENT）其微調音量調節+/-5dB；音量調節從01~80dB 4. 面板無任何按鍵,均為遙控器控制 5. 剛開機時為待機狀態，開機時音量為50dB狀態,各微調為0dB, 6. 按遙控器的REST鍵后,系統為開機時狀態， 7. PT2258音量衰減共80DB,按遙控器每按一次衰減1dB,

這個設計是使用Virtex-4實現DDR的控制器的，設計分為三個主要模塊：Front-End FIFOs,DDR SDRAM Controller和Datapath Module。其中主要是DDR SDRAM Controller,當然還有測試模塊。

Emdros is a text database middleware-layer aimed at storage and retrieval of "text plus information about that text." This information could be linguistic analyses or other annotations. Emdros provides an abstraction of text that makes it well suited to storing /syntactic analyses/ of text, but other linguistic information is supported as well. Emdros comes with a query-language, MQL, that enables powerful queries. Emdros acts as a middleware-layer between a client (not provided) and a database back-end. Currently, PostgreSQL, MySQL, and SQLite (2 and 3) are supported, but other back-ends can easily be added.

Wireless range extenders or wireless repeaters can extend the range of an existing wireless network. Range extenders can be strategically placed to elongate a signal area or allow for the signal area to reach around barriers such as those created in L-shaped corridors. Wireless devices connected through repeaters will suffer from an increased latency for each hop. Additionally, a wireless device connected to any of the repeaters in the chain will have a throughput that is limited by the weakest link between the two nodes in the chain from which the connection originates to where the connection ends
