Proudly published today: “Wave analysis tools” in
@methodsprimers.bsky.social. Learn how to choose the right methods for reliable, reproducible wave analyses across disciplines. Plus, meet WaLSA.tools, our open-source repository.
Dedicated to Bernhard Fleck’s inspiring contributions 🌟
Waves are everywhere around us. From the sub-nano scale of atoms to the vastness of the universe, we receive signals that are superpositions of waves.
This week's #Primer unveils the intricacies of wave #AnalysisTools shining a light on the best practices for #signalProcessing
