Digital communication — why it’s dominant

• Robustness: error detection and correction (FEC) significantly reduce effective error rates.
• Efficiency: advanced modulation (QAM, PSK, OFDM) and coding approach channel capacity.
• Flexibility: easy multiplexing, encryption, compression, and integration with digital processing.
• Scalability: software-defined radios and digital signal processing enable rapid feature upgrades.

1. Copyright Infringement: Distributing pirated PDFs violates intellectual property laws.
2. Malware/Viruses: Many PDF hosting sites (especially .tk or .xyz domains) carry malware that can infect your laptop or phone.
3. Outdated Content: Communication technology evolves rapidly. The 2008 edition does not cover modern topics like OFDM, 4G/5G physical layers, or software-defined radio (SDR).

• High noise immunity: Digital signals are less susceptible to noise and interference.
• High capacity: Digital systems can transmit large amounts of information with high accuracy.
