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.
Estimate the width of the frequency band that contains most of the power of a signal. For distorted signals, determine the power stored in the fundamental and the harmonics.
Measure Total Harmonic Distortion
Measure the total harmonic distortion of a sinusoidal signal.
