Linearization of transducer signals using an analog-to-digital converter

A simple method for linearizing analog electrical signals and transducer outputs as they are being converted to a digital format is described. It is based on the ratiometric property inherent to the analog-to-digital converter. The method gives satisfactory results in many cases, and the resulting circuits are simple and easily adjusted. It can be applied to correct the output of a digital readout meter and can provide a convenient alternative to digital linearization of signals
