想請教glitch和spike兩者的不同??

Jim_Lin

這兩個突波是在不同背景不同規模的瞬間電壓變化, 所發生的作用不同
Spike很明顯的電源上的突波, 所以影響也是電源上的
Glitch是載在控制訊號之上的突波, 多屬於干擾所造成
我們在玩遙控飛機時, Servo因感擾因素抖動了一下, 我們稱之為Glitch
(如果干擾很嚴重, 完全不受控制, 那一台就要兩眼開開, 準備投胎了   )

Electronics glitch
In electronics, a glitch is an electrical pulse of short duration that is usually the result of a fault or design error, particularly in a digital circuit. For example, many electronic components such as flip-flops are triggered by a pulse that must not be shorter than a specified minimum duration, otherwise the component may malfunction. A pulse shorter than the specified minimum is called a glitch. A related concept is the runt pulse, a pulse whose amplitude is smaller than the minimum level specified for correct operation, and a spike, a short pulse similar to a glitch but often caused by ringing or crosstalk.
