| Abstract: | About the trembling signal of keystroke in the design of digital control switch circuit, it will bring some wrong operation to the system. There is a research about the cause and the characteristic of trembling signal. Some methods of eliminate trembling signal are given, and the way of sampling base on low-lying frequency is a simple and steady circuit diagram, which can eliminate the trembling signal of digital control switch effectively. |
