1.1电子线路设计准则 电子线路设计者往往只考虑产品的功能,而没有将功能和电磁兼容性综合考虑,因此产品在完成其功能的同时,也产生了大量的功能性骚扰及其它骚扰。而且,不能满足敏感度要求。 电子线路的电磁
1.整机电路图功能 整机电路图具有下列一些功能: ①它表明整个机器的电路结构、各单元电路的具体形式和它们之间的连接方式,从而表达了整机电路的工作原理,这是电路图中最复杂的一张电路图。 ②它给出
在无线电设备中,对集成电路应用电路的识图是电路分析中的一个重点,也是难点之一。 1.集成电路应用电路图功能 集成电路应用电路图具有下列一些功能: ①它表达了集成电路各引脚外电路结构、元器件参数
电磁炉是应用电磁感应原理对食品进行加热的。电磁炉的炉面是耐热陶瓷板,交变电流通过陶瓷板下方的线圈产生磁场,磁场内的磁力线穿过铁锅、不锈钢锅等底部时,产生涡流,令锅底迅速发热,达到加热食品的目的。电磁炉
陶瓷滤波器按幅频特性分为带阻滤波器(又称陷波器)、带通滤波器(又称滤波器)两类。主要用于选频网络、中频调谐、鉴频和滤波等电路中,达到分隔不同频率电流的目的。具有Q值高,幅频、相 频特性好,体积小、信噪比
负反馈在电子电路中应用非常广泛。在放大电路中,利用负反馈可以稳定静态工作点和放大倍数,可以减小非线性失真、扩展频带,还可以改变放大器的输入阻抗和输出抗阻。如果一位电子工作者不了解负反馈,就说明对电子电
本文介绍的光耦是由发光二极管和光敏三极管组合起来的器件,发光二极管是把输入边的电信号变换成相同规律变化的光,而光脉敏三极管是把光又重新变换成变化规律相同的电信号,因此,光起着媒介的作用。由于光电耦合器
