额外设备

Unfortunately, too many engineers focus on the effect of harmonics on other electronic devices and tend to overlook the effect of the extra harmonic current that their electrical distribution systems need to carry.

不幸的是，太多的工程师都把注意力放到了其他电子设备产生的谐波干扰上，却往往忽略了电气分布系统载有的额外的谐波电流的影响。

Q3 and the PNP BJT (bipolar-junction transistor), Q1, effectively buffer the two SDA/SCL lines so that no extra current flows into the open-collector and -drain stages of the I2C devices that connect to the bus when they hold the lines down.

Q3、PNP BJT和Q1有效的缓冲SDA/SCL两条线，所以当连接总线的开集和开漏部分I2C设备的线持续为低时，没有额外的电流流进。
