'Spectrum': Spectral Analysis in Python
Thomas Cokelaer, Jürgen Hasch · The Journal of Open Source Software · 2017
Spectrum is a Python library that includes tools to estimate Power Spectral Densities.Although the use of power spectrum of a signal is fundamental in electrical engineering (e.g.radio communications, radar), it has a wide range of applications from cosmology (e.g., detection of gravitational waves in 2016), to music (pattern detection) or biology (mass spectroscopy).Methods available are based on Fourier transform, parametric methods or eigenvalues analysis.Although standard methods such as periodogram are available, less common methods (e.g.multitapering) are also implemented:
