摘要： Methods, circuits, and systems for determining the presence of a chopped input signal are disclosed. A digital signal generator can produce multiple digital signals when an alternating current (AC) signal input reaches multiple threshold voltages. The times at which the threshold voltages are reached can be determined by looking at the times at which the digital signals go high and low. The differences between the times at which the digital signals go high and low are used to determine if the AC signal input is a leading or trailing edge chopped signal. The AC input signal is a leading edge chopped signal when the difference between the times at which the digital signals go high is less than a predetermined time threshold, and is a trailing edge chopped signal when the difference between the times at which the digital signals go low is less than a predetermined time threshold.
摘要翻译：公开了用于确定斩波输入信号的存在的方法，电路和系统。当交流（AC）信号输入达到多个阈值电压时，数字信号发生器可以产生多个数字信号。达到阈值电压的时间可以通过查看数字信号变为高电平和低电平的时间来确定。使用数字信号变为高电平和低电平的时间之间的差异来确定AC信号输入是前导或后沿斩波信号。当数字信号变高的时间之间的差小于预定时间阈值时，AC输入信号是前沿斩波信号，并且当数字信号到达时间之间的差异时是后沿斩波信号低于预定时间阈值。
