Interactive Bartlett PSD Estimation Simulator

---

Estimate PSD by segmenting the signal into \(M\) non-overlapping segments, computing periodograms, and averaging:

\[ P_x(f) = \frac{1}{M \cdot N} \sum_{m=0}^{M-1} \left| \sum_{n=0}^{N-1} x_m[n] e^{-j 2 \pi f n} \right|^2 \]

Where \(x_m[n]\) is the m-th segment, \(M\) is number of segments, and \(N\) is the segment length.
