Transducer output signal processing using an eight-bit microcomputer

Transducer output signal handling involves corrections for input-output nonlinearities and corrections for the effects of disturbing variables, In this paper, the direct use of interpolating polynomials and the use of interpolating polynomials to generate multi-dimensional look-up tables for performing such corrections is discussed. Software implementation of these methods using an 8-bit microcomputer is described and results of simulations of two examples are presented.
