- central_frequency_unwindowed(data, fs)¶
Central frequency of a signal.
Computes the central frequency of the given data (a single waveform). The central frequency is a measure of the frequency where the power is concentrated. It corresponds to the second moment of the power spectral density function.
The central frequency is returned in Hz.
- data (ndarray) Data to estimate central frequency from.
- fs Sampling frequency in Hz.
