Abstract
A circuit for linearizing the meter movement of an analog meter provides a correction signal which is effective only in a predetermined portion of the meter movement range and which is adjustable to compensate for the specific linearity error in any given meter. Several of such circuits may be used wherein each of such circuits produces its primary effect in a portion of the meter range which is unaffected by adjustment in any of the other range portions. While the circuit finds its primary utility in providing correction signals to compensate for undesirable characteristics in display devices, analog or digital (with appropriate analog to digital conversion components) it may also be used to compensate for undesirable characteristics in display drive signals where that appears necessary.
