Abstract: A data transmission system for providing from a coarse analog signal representative of the cumulative angular position of a shaft, and from a fine analog signal representative of the noncumulative angular position of the shaft, a digital output indication of the cumulative position of the shaft. The coarse analog signal is utilized to provide the most significant digits and the fine analog signal is utilized to provide the least significant digits of the output display. Error correction means responsive to coarse and fine analog signals are provided for modifying the most significant portion of the output display to compensate for errors therein which may occur as a result of lower resolution in the encoder used to generate the coarse signal.
