Voltage is a difference between two points,but in electronics we often refer tovoltage at a point meaning the voltage difference between that point and a referencepoint of 0 V.

电压是两点间的差值, 但在电子学中我们常说的某一点上的电压其实是指这点和零伏参考点之前的一个电压差。

Noise is relatively easy to eliminate from digital signals because it is easy todistinguish from the desired signal which can only have particular values.

干扰相对较容易从数字电路中去除, 因为有用信号只取特定的值, 所以干扰就很容易与有用信号区别开。

The forward voltage drop of a diode is almost constant whatever the current passingthrough the diode so they have a very steep characteristic.

无论流过二极管的电流时多少, 二极管的正向压降几乎总是一个常数, 因此二极管有一个非常陡峭的特性

Small signal diodes can be damaged by heat when soldering ,but the risk is smallunless you are using a germanium diode.焊接时产生的热量损坏小信号二极管,但是除非你用的是锗二极管
