Abstract
The present disclosure concerns an electronic device connected to an antenna. The electronic device delivers a first amplitude-modulated analog signal of a signal captured by the antenna, the capture signal associated with an electromagnetic field exhibiting intervals at a minimum level. The electronic device includes a first circuit, a second circuit, and a third circuit. The first circuit delivers a second analog signal by rectification and filters the first analog signal. The second circuit delivers a first binary signal based on the demodulation of the second analog signal. The third circuit couples the antenna to a resistor during each pause. The resistance value of the resistor depends on the maximum amplitude of the electromagnetic field before the pause.
