  • APPARATUS AND METHOD FOR ENVELOPE DETECTION
    Publication number: 20130089127
    Abstract: An apparatus and a method are described for envelope detection used in fields including voice processing, image processing, data communication, and energy/data transmission. The apparatus and the method for envelope detection eliminate a carrier component from a modulated signal by performing a square-sum operation between two adjacent sampling signals among signals sampled from the modulated signal. The apparatus and the method detect an envelope of the modulated signal from the modulated signal in which the carrier component is eliminated.
