Abstract:
1. An offset compensating apparatus which compensates offset of an inverted signal and a non-inverted signal output from paired output ports of an electronic apparatus, the inverted and the non-inverted signals being in accordance with an input signal to the electronic apparatus, comprising: a selector for selecting one of the inverted signal and the non-inverted signal from the electronic apparatus; adjusting and comparing means, for obtaining a difference value between the inverted signal selected by the selector and a reference signal having no relationship to said inverted signal, and holding said difference value, and for conducting an error signal indicative of a difference between an non-inverted signal selected by the selector and a signal produced by reflecting said held difference value onto said reference signal; and calculating means for adding a value corresponding to said error signal to said input signal, wherein said calculating means includes a counter.
