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 ...

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 ...
