Abstract
The invention relates to a method for detecting high-frequency signals (22), comprising method steps as follows: dividing a high-frequency signal (22) into a raw signal (3) and a reference signal (4), attenuating the raw signal (3) into an attenuated signal (9), wherein the attenuating happens as a function of frequency of the raw signal (3) in accordance with an attenuation characteristic, rectifying the attenuated signal (9), so that a first direct voltage (15) is generated, rectifying the reference signal (4), so that a second direct voltage (16) is generated, ascertaining an attenuation from the ratio of the first and second direct voltages (15, 16), wherein the ratio corresponds to an attenuation factor for the attenuation of the raw signal (3), determining the frequency of the high-frequency signal (22) from the attenuation factor and an attenuation characteristic (17).
