Spectral Measurements

Channel power, bandwidth, mean frequency, median frequency, harmonic distortion

Use obw and powerbw to find the 90% occupied and 3-dB bandwidths of a signal. Compute the mean or median frequency of a power spectrum. Estimate the power over a given frequency band. Measure harmonic distortion. Estimate instantaneous frequency, spectral entropy, and spectral kurtosis.
