Amplitude Modulation

The codes in two files generate time and Frequency domain representation of three basic types of amplitude modulation i>Double SideBand Amplitude Modulation (Full Carrier) (DSBAM) ii>Double SideBand Suppressed Carrier (DSBSC) iii>Single SideBand (SSB) The message signals used are Combination of sinusoids of different frequency. Most authors use single tone modulation so give the initial concepts, but rarely do any one of them go beyond than. I believe the multi tone modulationrepresentation will help in visualizing how AM will work in case of voice modulation, which certainly is composed of number of harmonics.
