设计了水声信号发生系统中的功率放大电路,可将前级电路产生的方波信号转换为正弦信号,同时进行滤波、功率放大,使其满足换能器对输入信号的要求。该电路以单片机AT89C52,集成6阶巴特沃思低通滤波芯片MF6以及大功率运算放大器LM12为核心,通过标准RS232接口与PC进行通信,实现信号增益的程控调节,...
Power conversion by virtue of its basic role produces harmonics due to theslicing of either voltages or currents. To a large extent the pollution in t...
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...
