ABSTRACT:
A sensor provides an analog sensor output signal that is first converted by a A/D converter, followed by a digital signal processor having a digital signal output that is converted to an analog signal by way of a D/A converter so as to provide an analog information output signal indicative of a parameter quantity intended to be sensed. An analog dither signal and/or a digital dither signal is provided for modulating the A/D converter input signal and/or D/A converter input signal, respectively, separately, or in combination, to enhance dynamic range accuracy of the resultant analog information output signal representative of the quantity of the parameter intended to be sensed.
