Abstract
An indicator control circuit includes a signal conversion circuit for converting an analog signal corresponding to a predetermined physical quantity into first digital data and a digital filter circuit for generating second digital data from the first digital data in accordance with a predetermined filter characteristic. An intermediate digital data is obtained during a process in which the second digital data is generated from the first digital data. The digital filter circuit includes operating circuit for operating the intermediate digital data so that a relationship between the first digital data and the second digital data has a hysteresis. The second digital data generated by the digital filter circuit is used for indicating the predetermined physical quantity on an indicator.
