可编程逻辑 数字与模拟电路设计技巧
数字与模拟电路设计技巧IC与LSI的功能大幅提升使得高压电路与电力电路除外,几乎所有的电路都是由半导体组件所构成,虽然半导体组件高速、高频化时会有EMI的困扰,不过为了充分发挥半导体组件应有的性能,电路板设计与封装技术仍具有决定性的影响。 模拟与数字技术的融合由于IC与LSI半导体本身的高速化,同时为了使机器达到 ...

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 ...

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 ...
