The book introduces three parts of telecommunications. Analog Telecommunications Signals and spectra; linear-continuous and exponential waves modulations; AM and FM systems noise; TDM and FDM; pulse modulation; sampling theorem; pulse amplitude and pulse width modulations; pulse position 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; coding effi ciency; error probability; error detection; and error correction. Multimedia Telecommunications Telecommunications in the context of multimedia systems.
