In this paper we offer a method for constructing functions with many gaps in their supports and in the supports of their Fourier transform. As a result we answer a question of Benedicks [Ben1] and we ...

Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

THIS article suggests that Walsh functions 1–3 might be used in transform Spectroscopy 4–6 to replace the sinusoidal functions appearing in the Fourier transform. We think this might be the case ...
