An abnormal signal detecting device, comprising a signal sampling and conversion circuit for sampling a predetermined number of data points along an analog signal and generating digital sampled data signals representative thereof; a memory circuit, connected to the signal sampling and conversion circuit, for storing the digital sampled data; and a consistency detecting circuit, connected to the memory circuit, for comparing at least three consecutive digital sampled data signals and generating an output representing an abnormal condition whenever at least three consecutive digital sampled data signals are the same. |
