在许多μC应用中。传感器的模拟输入信号经过信号调节器调节后送入μC进行处理。一般信号调节的最后一级是一个器件,它的任务是将信号电平转换成μC输入端可以接受的电平。这个器件通常就是比较器。此信号通道通常是在一定的可编程时段开启或闭合。为达到此目的,可以采 In many μC applications. The sensor’s analog input signal is conditioned by the signal conditioner and fed to μC for processing. The final level of general signal conditioning is a device whose task is to convert the signal level into an acceptable level at the μC input. This device is usually a comparator. This signal path is usually open or closed for a certain programmable period. To achieve this goal, it can be taken
