This article explains how windowing artifacts distort spectra and mislead interference analysis.Why Welch PSD Alone Often Misleads Tonal Detection in Noisy DSP Systemshttps://blog.signal-forge.app/posts/why-welch-psd-misleads-tonal-detection/Wed, 18 Feb 2026 00:00:00 +0000https://blog.signal-forge.app/posts/why-welch-psd-misleads-tonal-detection/Welch PSD is widely used for spectral estimation, but averaging effects and estimator variance often mislead tonal detection in real noisy signals. This article explains why and how deterministic PSD + STFT workflows fix it.
