Operation of amplitude modulator is based on the use of the second-order delta-sigma modulator. Polar delta-sigma bit-stream is nonlinearly processed in the negative feedback of delta-sigma modulator to produce an amplitude modulated signal. All information about modulating signal is contained in both envelope and carrier of the modulated signal. Thus, because of a dual nature of modulated signal, one can detect zero-crossings of a carrier, using sign detector, to obtain a polar delta-sigma bit stream. By demodulation (low-pass filtering) this polar bit-stream modulating signal is obtained. The main advantages of a proposed system are: simple digital amplitude modulator and simple demodulator which can be integrated in one IC chip. Because of non-positional nature of delta-sigma bit stream, proposed system is robust to channel errors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Amplitude modulation system and apparatus","description":"Disclosed is the delta-sigma amplitude modulation system.
