Abstract

A reader for identifying passive transponders includes an antenna for receiving a first signal (Tx) from the reader and for transmitting a second signal (Rx). The reader includes: a time base generating a sinusoidal signal, a control circuit, a modulator for transmitting to the control circuit data to modulate the sinusoidal signal so as to generate a signal carrying commands which, when it is received by the antenna of the transponder, forms the first signal (Tx), a demodulator, a decoder, a communication interface and an antenna. The demodulator, which is connected to the antenna to receive the second signal (Rx), includes two multipliers, one being of the inverter type, and an adder designed to combine the data derived from the multipliers. A system including first and second devices that communicate by way of a modulated transmitted signal is also described.
