Abstract:
    An apparatus and a method for processing signals of an analog encoder for generating quadrature signals to control a rotation of a motor using the analog encoder are provided. The apparatus for processing signals of the analog encoder includes a pattern generation unit of the analog encoder generating an encoder waveform corresponding to a waveform of the output signals by receiving the output signal of the analog encoder including at least one channel and sampling the received signals at regular intervals, and a generation unit for generating a status lookup table receiving the encoder pattern and generating the status lookup table including a predetermined number of information pieces on the encoder status based on the received encoder pattern, wherein the quadrature signals are generated by comparing feedback output signals to the information on the encoder status. The apparatus is adaptable to characteristics of various encoders.
