Amplitude Modulation

Time and Frequency domain representation of AM.

Description

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 modulation
representation will help in visualizing how AM will work in case of voice modulation, which certainly is composed of number of harmonics.
Any suggestion are welcome at [e-mail].

It was nice to see such a clear, basic example contain more then one message signal.

good job dude

verrrrrrrry gooooood friend

[izak]

why if i am using 3300 Hz as fc and 2000 Hz as fm, matlab cannot show the figure well??
 how is the solution?

what is the correlation between N and fs??

thank you,,
