A very common method of transmitting information known as amplitude modulation (AM) will be examined in this chapter. AM was the first widespread technique used in commercial radio broadcasting. The approaches presented here are particularly suited for implementation by digital signal processors. More complete discussions of AM and analog implementations can be found in the textbooks on communication systems suggested at the end of this chapter.
