Proceedings of the American Mathematical Society, Vol. 132, No. 12 (Dec., 2004), pp. 3491-3502 (12 pages) We educe an orthonormal system of step functions for the interval [0,1]. This system contains ...

Most engineering labs have digital oscilloscopes, but many engineers don’t fully explore their features. Among the more interesting features of a digital oscilloscope is its math channel, which can ...

The methods presented in this paper provide an improved technique for fitting a continuous function to discontinuous step functions so often evolving from empirical studies such as estimation of ...
