Trainable Fractional Fourier Transform

A differentiable fractional Fourier transform (FRFT) implementation with layers that can be trained end-to-end with the rest of the network. This package provides implementations of both fast ...

Using an oscilloscope’s time, frequency, and statistical measurement domains

Multiple domains provide designers and test engineers with complementary views of acquired signals. Oscilloscopes originated as instruments that measure electrical signals in the time domain. The ...

Differentiable short-time Fourier transform with respect to the hop length

Abstract: In this paper, we propose a differentiable version of the short-time Fourier transform (STFT) that allows for gradient-based optimization of the hop length or the frame temporal position by ...

Graph Fractional Fourier Transform: A Unified Theory

Abstract: The fractional Fourier transform (FRFT) parametrically generalizes the Fourier transform (FT) by a transform order, representing signals in intermediate time-frequency domains. The FRFT has ...
