Welch's Method is a technique used for estimating the power spectral density (PSD) of a signal. It improves upon the traditional periodogram method by dividing the data into overlapping segments, applying a windowing function to each segment, and then averaging the results to produce a smoother and more reliable estimate of the spectrum. This method is particularly useful for analyzing signals that are corrupted by noise, making it a key tool in frequency-domain analysis.
congrats on reading the definition of Welch's Method. now let's actually learn it.
