Abstract: The modulation feature extraction of signals is a very important topic in communication area. With the recent year development of science and technology ,modem technique has made rapid progresses. The present paper introduces basic methods of signal modulations and demodulations,principles of important modulation and demodulation approaches,important applications in life. At the end of the present paper is it my realized several groups of signal modulations and demodulations according to the above related theory ,using LabVIEW programming approaches.
