本文提供了一种增量型光电编码器的通用数字滤波电路。从增量式光电编码器本身的输出信号误差和对通用鉴相滤波电路的元件触发误差特性入手,通过详细地分析,深入地揭示了该电路的误触发原因,并给出了防止误触发计数的条件。
This article provides an incremental digital optical encoder universal digital filter circuit. Starting from the error of the output signal of the incremental photoelectric encoder itself and the component triggering error of the common phase detection filter circuit, the reason of false triggering of the circuit is revealed in detail and the measures to prevent false triggering count conditions of.
