11. Alternatively, the signals could be separated using a demodulator in single sideband mode. 12. A modem stands for MOdulator DEModulator . 13. A demodulator separates sound from video. 14. Then there is only an ASK demodulator and the two flows of data are merged back. 15. Many things can act as a demodulator , if they pass the radio waves on nonlinearly. 16. At the other end a demodulator reconverted the sound into ECG with a good gain accuracy. 17. Significant conditions are recognized by an appropriate device called a receiver, demodulator , or decoder. 18. Otherwise just find a couple of old fax machines and cannibalize the modulator / demodulator circuits. 19. A multi-loop modulator / demodulator feedback approach was used to generate an accurate arcsin signal. 20. Moreover, it is possible to develop a demodulator which can process signals with different modulation types.
