Channel power, bandwidth, mean frequency, median frequency, harmonic distortion
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 bandwidth, instantaneous frequency, spectral entropy, and spectral kurtosis.
Power and Bandwidth
|Equivalent noise bandwidth|
|Estimate instantaneous bandwidth|
|Estimate instantaneous frequency|
|Spectral entropy of signal|
|Spectral kurtosis from signal or spectrogram|
|Streamline signal frequency feature extraction|
- 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.
