晶振輸出波形是怎么樣的?晶振匹配電容如何計算?相關問答:

問題:用石英晶體振蕩器如何產生1Hz脈沖的

回答:石英晶體振蕩器分頻就可以產生1Hz脈沖的,你的晶振頻率是多少啊,說了才好給你電路圖。一般用來產生1Hz脈沖的晶振都用的32768HZ的。

問題:什么是晶體振蕩器?

回答:澳门百家乐攻略晶體振蕩器是指從一塊石英晶體上按一定方位角切下薄片(簡稱為晶片),石英晶體諧振器,簡稱為石英晶體或晶體、晶振;而在封裝內部添加IC組成振蕩電路的晶體元件稱為晶體振蕩器。其產品一般用金屬外殼封裝,也有用玻璃殼、陶瓷或塑料封裝的。

問題:晶體振蕩器有什么作用?

回答:晶振在應用具體起到的作用,微控制器的時鐘源可以分為兩類:基于機械諧振器件的時鐘源,如晶振、陶瓷諧振槽路;RC(電阻、電容)振蕩器。一種是皮爾斯振蕩器配置,適用于晶振和陶瓷諧振槽路。另一種為簡單的分立RC振蕩器。

問題:正弦波振蕩器的簡介

回答:正弦波振蕩器可分為兩大類:一類是利用反饋原理構成的反饋振蕩器,它是目前應用最廣的一類振蕩器;另一類是負阻振蕩器,它將負阻抗元件直接連接到諧振回路中,利用負阻器件的負阻抗效應去抵消回路中的損耗,從而產生出正弦波振蕩。

問題:澳门百家乐攻略石英晶體振蕩器是利用石英晶體的什么工作的

回答:澳门百家乐攻略石英晶體振蕩器又名石英諧振器,簡稱晶振,是利用具有壓電效應的石英晶體片制成的。這種石英晶體薄片受到外加交變電場的作用時會產生機械振動,當交變電場的頻率與石英晶體的固有頻率相同時,振動便變得很強烈,這就是晶體諧振特性的反應。利用這種特性,就可以用石英諧振器取代LC(線圈和電容)諧振回路、濾波器等。
