<p>The invention relates to a method and a device for detecting at least one first input signal superimposed on at least one second signal, the method comprising the steps of providing said at least one first input signal superimposed on at least one second signal to at least one half-wave rectifier; transforming, in said at least one half-wave rectifier, said at least one first input signal superimposed on at least one second signal into a half-wave rectified signal; providing said half-wave rectified signal to an envelope detector; and transforming, in said envelope detector, said half-wave rectified signal into an envelope signal.
In this way, a simpler and cheaper method and/or device are provided for e.g. detecting a transmitted information signal superimposed on a high frequency carrier signal.</p> |
