<p>The electronics has a transmitting/receiving device to receive an amplitude-modulated request signal (25). An evaluation device decodes the request signal and generates an envelope signal (33) from the decoded signal. The evaluation device has a gray counter that has an input to receive the request signal. A shift register (41), which receives an output from a digital counter, has multiple register stages. A logic circuit (43) receives an input from the register stage of the shift register and provides an output representing a decoded value of the request signal provided to the transmitting/receiving device.</p> |
