Abstract

A transmitting apparatus for transmitting a frequency-modulated signal is provided. The transmitting apparatus includes a pilot tone generation device for generating a pilot tone. The transmitting apparatus also includes a modulation device for obtaining the generated pilot tone and a modulating useful signal and for generating a frequency-modulated signal based on a combination of the generated pilot tone and the modulating useful signal. The generated pilot tone has a frequency outside a frequency range of the modulating useful signal in order to vary a frequency range of the frequency-modulated signal.
