Altering the frequency of the carrier. FM provides better noise immunity than AM.
The book covers both classical analog systems (AM, FM, Superheterodyne receivers) and modern digital systems (PCM, ASK, FSK, PSK, QPSK, Spread Spectrum). It even touches on optical fiber and satellite communication in later editions.
