Abstract: A method of protection from noise of a digital signal generated by a comparator, including the steps of generating an output signal that switches from a first logic state to a second logic state at a first switching of logic state of the digital signal; detecting a change from the first logic state to the second logic state of the output signal; and inhibiting further switchings of the output signal for a first time interval after the change from the first logic state to the second logic state.

Abstract translation: 一种防止由比较器产生的数字信号的噪声的方法，包括以下步骤：在数字信号的逻辑状态的第一次切换时产生从第一逻辑状态切换到第二逻辑状态的输出信号; 检测从所述第一逻辑状态到所述输出信号的第二逻辑状态的变化; 以及在从所述第一逻辑状态到所述第二逻辑状态的改变之后，禁止所述输出信号进一步切换第一时间间隔。
