Abstract
The present invention describes a device for detecting the power of a first signal at a given frequency. The device comprises a first circuit means for detecting the envelope of the first signal and a second circuit means coupled to the first circuit means and suitable for generating a second signal proportional to the average of the envelope detected. The second signal is proportional to the square root of the average power of the first signal.
