在数字电子技术中，如何表示低电平时 "触发"和高电平时"非触发"的信号？

How to denote signals that are "asserted" when low and "deasserted" when high in digital electronics?

1、信号名称上的横条： 信号名称上的水平条（或线）是表示信号为低电平有效的常用方法。

1, Bar Over the Signal Name: A horizontal bar (or line) over the signal name is a common way to indicate that a signal is active-low.

2、后缀符号： 在信号名称中添加 _B、_N 或 # 等后缀。例如：

2, Suffix Notation: Adding a suffix such as _B, _N, or # to the signal name. For example:

CTS_B

CTS_N

CTS#

3、反转符号： 有时，在门或器件的输入/输出引脚上放置一个气泡（圆圈），表示信号为低电平有效。这通常与上述符号结合使用。

3, Inversion Symbol: Sometimes, a bubble (circle) is placed at the input/output pin of a gate or device to indicate that the signal is active-low. This is often used in combination with the above notations.
