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.

Parameters

• data (ndarray) – Data to estimate central frequency from.

• fs – Sampling frequency in Hz.

Returns

cfreq - Central frequency in Hz
