Abstract

A circuit for transducer linearizer tasks has been designed and built using discrete components. It is implemented by a Radial Basis Function Network (RBFN) with three basis functions. The application in a linearized thermistor showed that the network has good approximation capabilities. The circuit advantages are the amplitude, width and center
