Abstract
A method and apparatus for linearizing an analog signal. The signal is converted into a digital form and digital gain and offset words are fetched based upon the value of the measurement signal and any other parameters which affect linearity, such as temperature for example. The digital gain and offset words are converted to analog values and inserted into an analog signal path of the measurement signal.
