How to debounce high-frequency events in JavaScript

Optimizing debounce in JavaScript applications focuses on enhancing performance and managing memory efficiently. Key strategies include cleaning up event listeners, using mutable state for closures, and centralizing event handling. Implementing debounce with async operations and integrating with requestAnimationFrame can further improve responsiveness and user experience.

How to apply Fourier transforms using scipy.fftpack in Python

Fourier transform results consist of complex arrays encoding magnitude and phase for frequency bins. Magnitude reveals dominant frequencies, while phase relates to signal timing. Frequency resolution depends on sampling rate and sample count. Techniques like Welch’s method improve spectral estimates for noisy signals.
