While the Fourier transform gets all the attention, there are other transforms that engineers and mathematicians use to transform signals from one form to another. Sometimes you use a transform to ...

The Hilbert transform and raised-cosine filter, staples of signal processing for decades, are no longer just textbook concepts—they are driving innovation in quantum computing, neural networks, and ...

The Hilbert-Huang transform (HHT) is widely used for time-frequency analysis of blasting seismic wave signals due to its unique adaptability. However, blasting seismic wave signals are typical ...

Time-frequency signal processing is concerned with analysing how the spectral content of a signal evolves over time, offering a unified framework that bridges classical Fourier analysis with ...
