level trigger 与 edge trigger 的区别

Level Trigger:
1) The input signal is sampled when the clock signal is either HIGH or LOW. 
2) It is sensitive to Glitches. 
Example: Latch. 

Edge Trigger:
1) The input signal is sampled at the RISING EDGE or FALLING EDGE of the clock signal. 
2) It is not-sensitive to Glitches. 
Example: Flipflop. 

翻译过来一个叫做条件触发（

Level Trigger），一个叫做边缘处罚 （

Edge Trigger）
