ABSTRACT:
A system compatible for different types of signals relates to a motor includes a differential amplifier, a comparator, and a transmitting device. The differential amplifier is configured to receive one of a differential digital pulse signals pair and a differential analog signals pair. The differential digital pulse signals pair is converted to a first digital signal, and the differential analog signals pair is converted to an analog signal by the differential amplifier. The comparator is configured to convert the analog signal into a second digital signal. The first digital signal is received and outputted by the comparator. The transmitting device is configured to convert a data signals pair to a binary code, and convert differential reference digital signals pairs to reference digital signals. The reference digital signals, the first and second digital signals are received by an external computing device.
