Abstract: Modulation is the transmission of information to be loaded onto a high-frequency(carrier) signal in the process.Amplitude modulation using signal to control the rate of carrier,with its linear modulation signal changes,and maintain the same carrier frequency.In the amplitude modulation,in accordance with the strength of signals in the spectrum of different components,it is divided into ordinary AM(amplitude modulation standard AM),with inhibition of bilateral carrier AM(DSB),the carrier single sideband suppression AM(SSB).The main difference is the different methods and structure of the spectrum.
