浮接信号与差分信号的区别

ricken

今天有看到一段对浮接信号和差分信号的定义,想了半天,还是不是太了解,请高人指点一下:
这一段是有关浮接信号进行单端模式接法的.
The single-ended mode has only one input relative to ground and is suitable
for connecting with a floating signal source. A floating source is one that does
not have any connection to ground.
下面是有关差分接法的.
A differential mode must be used when the signal source is differential. A
differential source means that the ends of the signal are not grounded. To
avoid the danger of high voltages between the local ground of the signal and
the ground of the PC system, a shorted ground path must be connected.

差分是为了抗干扰更强些，因为如果有干扰，二条输入均有，一起接入，就有抵消的功能！
