【正文】 電阻)，輸出電壓增大。 利用集成運(yùn)放和二極管的正向伏安特性的非線性可實(shí)現(xiàn)電路的自動(dòng)起振和自動(dòng)穩(wěn)幅，從而實(shí)現(xiàn)頻率可調(diào)的正弦波產(chǎn)生電路圖如下所示。經(jīng)反饋后，在端2得到一個(gè)同頻率的正弦信號(hào)Uf，如果Uf與Ui大小相等，相位相同，即Uf=Ui，那么當(dāng)開關(guān)S從1倒向2后，放大電路的工作狀將保持不變，從而使輸出端電壓U。工作原理如下；加入開始時(shí)，放大電路輸入端接一正弦信號(hào)U，經(jīng)放大后，在輸出端等到正弦電壓U。 Squarewave sine wave transformation circuit。AbstractSine wave signals is more mon in life, and the square wave is also familiar with in our .study and life, and the key is how to convert the sine wave of our everyday ChengFangBo and apply what they have learned by conversion of the digital circuit of clock square wave count.Through this course designed to consolidate and deepen the understanding of basic knowledge of electronic electrician technology lesson and extension, and improve our prehensive ability to use knowledge. Cultivate our ch
