Abstract

A device and a method for frequency analysis. The frequency of an output signal is divided, and an auxiliary signal with a known frequency is subtracted from the low-frequency signal to define a low-frequency differential signal. The output frequency is determined on the basis of the frequency of the low-frequency differential signal.
