In this article we will study the spectral properties of a deterministic signal exponentially damped in the past and in the future (the damping in the future is controlled by a time constant). The ...

Proceedings of the American Mathematical Society, Vol. 143, No. 6 (JUNE 2015), pp. 2403-2410 (8 pages) We present a characterization of the sets that appear as Fourier spectra of measures in terms of ...

[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video ...
