We show that a stationary signal concept such as the Fourier transform (FT) can be linked to a time-varying (TV) concept such as linear TV filtering.

Time-varying filter interpretation of Fourier transform and its variants · P. Ghosh, T. Sreenivas · Published in Signal Processing 1 November 2006 · Computer ...
We have shown that the FT and its variants, including STFT, can be interpreted as LTV filter operations. To get some insight into the TV filters corresponding ...
Time-varying filter interpretation of Fourier transform and its variants.
This paper is an attempt to summarize two established processing techniques to obtain these quantities based on a time sampled data stream. The first class of ...
Missing: interpretation variants.
The proposed filter is shown to have a superior performance when compared to the filter based on masking the STFT. The sensitivity of the filter is studied.
As with the Fourier transform interpretation, the filtering view also allows us to easily deduce a number of STFT properties. In particular, we view X(n, w) ...
This primer discusses the needs and analysis benefits of this technique, explores how it works, and how it can be used most effectively to see time-varying RF ...
