Technique for sensing the rotational speed and angular position of a rotating wheel
摘要:
A method of processing a pulse train output signal provided by a non-contact sensor that senses the rotational speed and angular position of a rotating wheel includes comparing the amplitudes of the pulses with a variable switching threshold value, and adjusting the value of the variable switching threshold value if the difference between the amplitudes of two successive pulses exceeds a maximum value.
