central_frequency_unwindowed(data, fs)[source]¶

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.

Parameters:	data (`ndarray`) Data to estimate central frequency from. fs Sampling frequency in Hz.
Returns:	cfreq - Central frequency in Hz
