Automobiles, aircraft, marine vehicles, uninterruptiblepower supplies and telecom hardware represent areasutilizing series connected battery stacks. These stacksof individual cells may contain many units, reaching potentialsof hundreds of volts. In such systems it is oftendesirable to accurately determine each individual cell’svoltage. Obtaining this information in the presence of thehigh “common mode” voltage generated by the batterystack is more diffi cult than might be supposed.

在Multisim 10軟件環境下，設計一種由運算放大器構成的精確可控矩形波信號發生器，結合系統電路原理圖重點闡述了各參數指標的實現與測試方法。通過改變RC電路的電容充、放電路徑和時間常數實現了占空比和頻率的調節，通過多路開關投入不同數值的電容實現了頻段的調節，通過電壓取樣和同相放大電路實現了輸出電壓幅值的調節并提高了電路的帶負載能力，可作為頻率和幅值可調的方波信號發生器。Multisim 10仿真分析及應用電路測試結果表明，電路性能指標達到了設計要求。 Abstract: Based on Multisim 10， this paper designed a kind of rectangular-wave signal generator which could be controlled exactly composed of operational amplifier， the key point was how to implement and test the parameter indicators based on the circuit diagram. The duty and the frequency were adjusted by changing the time constant and the way of charging and discharging of the capacitor， the width of frequency was adjusted by using different capacitors provided with multiple switch， the amplitude of output voltage was adjusted by sampling voltage and using in-phase amplifier circuit，the ability of driving loads was raised， the circuit can be used as squarewave signal generator whose frequency and amplitude can be adjusted. The final simulation results of Multisim 10 and the tests of applicable circuit show that the performance indicators of the circuit meets the design requirements.

基本的編輯工具(GENERAL EDITING FACILITIES) 對象放置(Object Placement) ISIS支持多種類型的對象，每一類型對象的具體作用和功能將在下一章給出。雖然類型不同，但放置對象的基本步驟都是一樣的。 放置對象的步驟如下(To place an object:) 1.根據對象的類別在工具箱選擇相應模式的圖標(mode icon)。 2. Select the sub-mode icon for the specific type of object. 2、根據對象的具體類型選擇子模式圖標(sub-mode icon)。 3、如果對象類型是元件、端點、管腳、圖形、符號或標記，從選擇器里(selector)選擇你想要的對象的名字。對于元件、端點、管腳和符號，可能首先需要從庫中調出。 4、如果對象是有方向的，將會在預覽窗口顯示出來，你可以通過點擊旋轉和鏡象圖標來調整對象的朝向。 5、最后，指向編輯窗口并點擊鼠標左鍵放置對象。對于不同的對象，確切的步驟可能略有不同，但你會發現和其它的圖形編輯軟件是類似的，而且很直觀。 選中對象(Tagging an Object) 用鼠標指向對象并點擊右鍵可以選中該對象。該操作選中對象并使其高亮顯示，然后可以進行編輯。
