Abstract

An apparatus configured to determine a measure of the frequency of an electrical signal, the apparatus configured to; based on a plurality of samples of the electrical signal (102), determine a Hilbert transformation (200) to obtain a value for each of the samples of the electrical signal for use as an imaginary representation (201) of each of the samples of the electrical signal and combine (202) each said imaginary representation with a corresponding real representation (203) of the samples of the electrical signal to form a complex representation of the electrical signal (204); perform a Fourier transform (205) on each said complex representation of the samples of the electrical signal and determine a phase angle therefrom (206); determine a measure of the frequency of the electrical signal based on a derivative (207) of the phase angle with respect to time.
