可编程逻辑 PCB被动组件的隐藏特性解析
PCB 被动组件的隐藏特性解析
传统上，EMC一直被视为「黑色魔术（black magic）」。其实，EMC是可以藉由数学公式来理解的。不过，纵使有数学分析方法可以利用，但那些数学方程式对实际的EMC电路设计而言，仍然太过复杂了。幸运的是，在大多数的实务工作中，工程师并不需要完全理解那些复杂的数学公式和存在于EMC规范中的学理 ...
可编程逻辑 PCB设计经典资料
本文将接续介绍电源与功率电路基板，以及数字电路基板导线设计。宽带与高频电路基板导线设计a.输入阻抗1MHz，平滑性(flatness)50MHz 的OP增幅器电路基板图26 是由FET 输入的高速OP 增幅器OPA656 构成的高输入阻抗OP 增幅电路，它的gain取决于R1、R2，本电路图的电路定数为2 倍。此外为改善平滑性特别追加设置可以加大噪讯ga ...
测试测量 基于MASON公式的多功能二阶通用滤波器设计
基于通用集成运算放大器，利用MASON公式设计了一个多功能二阶通用滤波器，能同时或分别实现低通、高通和带通滤波，也能设计成一个正交振荡器。电路的极点频率和品质因数能够独立、精确地调节。电路使用4个集成运放、2个电容和11个电阻，所有集成运放的反相端虚地。利用计算机仿真电路的通用滤波功能、极点频率和品质因数的 ...

DSP音频处理示例The benefits of real-time analysis provided by DSP/BIOS are often required in programs that
were engineered without it. When the program is not built from the ground up using the
DSP/BIOS kernel and real-time analysis features, the lack of familiarity prevents engineers
from reaping t ...
