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.
Functions
Topics
- Measure the Power of a Signal
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.
