FIELD: electronic engineering. SUBSTANCE: amplitude-modulated signal carrier is compared with threshold value. As soon as it become equal to threshold value, pre-scale amplitude-modulated signal value is stored and used as demodulated signal. Scaling factor is inversely proportional to threshold value. Demodulator implementing this method has comparison unit 1, reference signal unit 2, storage unit 3, and scaling unit 4. EFFECT: improved demodulation accuracy. 3 dwg
