Abstract

The spline functions are a useful tool for signal processing. This article aims to provide a tutorial over spline operators used as an approximation mechanism in analysis of analogical system circuits that is geared to a signal processing audience. The algorithm of spline operators is developed using differential equation of an electrical circuit, in particular with constant coefficients. We describe the mathematical method to develop the design of spline operators and we build those operators, using virtual instrumentation available in Lab View software.
