Advances in digital technology have revolutionized wireless communication and increased the complexity of information coding. Wireless communication systems now incorporate both analog and digital principles in ways that provide a seamless flow of information (both voice and data) between transmitter and receiver. In this session a non-mathematical overview of modulation techniques and their application will be presented. The intended audience is Communication and IT technicians that often must work with complex modulated signal, but have limited exposure or practical background in modulation theory. Topics covered will include: characteristics of analog and digital signals; analog modulation (amplitude, frequency, and phase); digital modulation (PAM, PWM, PPM, PCM, DPCM, and Delta); digital baseband and carrier modulation techniques, and digital coded signals (ASK, FSK, PSK, DPSK, M-ary and QAM signals). Those attending this session will acquire a fuller understanding of modulation techniques and their role in evolving communication systems.
