5. Hilbert transform as an infinite matrix

Hilbert transform as an infinite matrix — johndcook.com · 22h ago · ⭐ 19/30 This article explores a novel mathematical perspective on the Hilbert transform, conceptualizing it as an infinite matrix. Building on previous discussions linking the Hilbert transform to Fourier series, it suggests that if a function’s Fourier series is represented in a specific way, its Hilbert transform’s Fourier series can be derived. This approach provides an alternative framework for understanding how the Hilbert transform operates on functions. The article aims to offer a deeper, more abstract insight into this fundamental signal processing operation. 🏷️ Hilbert transform, Fourier series, mathematics, signal processing —
