This patent discloses an electronic system for scanning across a range of received signals and obtaining a digital representation of a predetermined position, for example, the mid-point of the bandwidth of the received signal, without having to ascertain directly the frequency at said predetermined position. The system can include a homodyne receiver zero-beat reception using a voltage controlled local oscillator or a superheterodyne receiving using a local oscillator for producing an intermediate frequency.
