Analog, Digital and Multimedia Telecommunications

The book introduces three parts of telecommunications.Analog Telecommunications Signals and spectra; linear-continuous andexponential waves modulations; AM and FM systems noise; TDM and FDM; pulsemodulation; sampling theorem; pulse amplitude and pulse width modulations; pulseposition and pulse code modulations; PSK; FSK; data transmission; base-band transmission;error control; circuit noise; noise sources; noise fi gure; and noise temperature.Digital TelecommunicationsElements of a digital telecommunications system;digital modulations; delta modulation; phase shift keying techniques (BPSK, DPSK,QPSK, DQPSK, DEPSK, M-array PSK); frequency shift keying (BFSK, M-array FSK);QAM; multiplexing techniques; information theory and coding; amount of information;information transfer rate; baud rate; channel capacity and Shannon theorem; codingeffi ciency; error probability; error detection; and error correction.Multimedia Telecommunications Telecommunications in the context ofmultimedia systems.
