Digital Spectra Analysis

This is a hands-on project, applying Power Spectral Density (PSD) functions including

• Blackman-Tukey
• Welch Periodogram
• Yule-Walker
• Burg(Harmonic)
• Covariance PSD estimate
• Covariance PSD estimates
• Adaptive Least Mean Squares
• MUSIC PSD estimates

Data Set

• 1: a 128-point real data sequence consisting of unit-amplitude sinusoids at 10Hz, 11Hz, and 25Hz. Sampling frequency fs=64 /second.
• 2: a data record identical to Data Set #1, but add white noise such that signal-to-noise radio(SNR) is 0 dB.
