MULTIPLICATIVE APPROXIMATION METHOD OF FUNCTIONAL DEPENDENCIES BY LINE SEGMENTS

The article is devoted to the approximation problems of functional dependencies during conversions performed in intelligent measurement devices. Non-linearities are essential parts most control processes and systems. When using a nonlinear transmitter with conversion function information systems used various fields, it necessary perform operations on numbers microprocessors/microcontrollers direct indirect measurements. For this purpose, methods used. purpose describe functions simpler, more convenient way for utilization calculations, an insignificantly small loss accuracy. Existent linearization, although some them effective, can be burdensome implementation microprocessor-based Here, one proposed by line segments proposed. In method, range argument changes divided into segments, coordinate system bisector, remaining within function, swapped approximation. Having involved few simple mathematical operations, method implemented efficiently approximations
