什么是双脉冲编码器？

硬件: Multifunction DAQ (MIO)

问题: 我使用的板卡文档中说其支持双脉冲编码器。这是什么编码器，是否与向上/向下编码器相同？

解答: A two pulse encoder is a motion encoder that has two channels: channels A and B. A pulse on channel A causes the counter to increment on its rising edge. A pulse on channel B causes the counter to decrement on its rising edge, as shown in the following figure. This type of encoder is also referred to as an up down encoder.双脉冲编码器是一种运动编码器，它有两个通道：通道A和B。通道A上的脉冲使计数器在其上升沿时增加。通道B上的脉冲使计数器在其上升沿时减小，如下图所示。这种类型的计数器也被称为向上向下编码器。
