Adventures in the (not so) Complex Space


We report on the progress of a constructive mechanization for a small subset of signal processing theory, built upon the SSREFLECT and MATHCOMP libraries. The development was started to provide mechanized semantics for audio programming languages. Currently, we have formalized several standard properties of the Discrete Fourier Transform, such as its unitary matrix form and its power and convolution theorems. Future goals include transfer functions and constant overlap-add processing. At the workshop, we aim to discuss the needs and limits of our current approach, surveying some mathematical concepts not covered by existing libraries, and similar efforts in other frameworks and theorem provers.
