The authors detail how digital bits are mapped to analog waveforms for transmission, covering Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), Phase Shift Keying (PSK), and Quadrature Amplitude Modulation (QAM). 4. Noise in Communication Systems

Mixes both amplitude and phase shifts to transmit multiple bits per symbol, drastically improving spectral efficiency. 4. Key Comparative Metrics Analog Communication Digital Communication Signal Type Continuous time-varying waves Discrete binary states (0 and 1) Noise Vulnerability High; noise cannot be easily separated from the signal Low; signals can be regenerated using repeaters Bandwidth Requires less bandwidth for basic transmission Requires higher bandwidth for equivalent raw data Hardware Complex analog circuits (inductors, capacitors) Flexible digital circuits (DSP, microprocessors, FPGAs) Security Hard to encrypt; relies on physical scrambling Easy to encrypt using advanced cryptographic algorithms Error Correction Not possible Supported via Forward Error Correction (FEC) codes 5.
