In recent times, digital transmission systems have been increasingly used for the transmission of analog signals such as audio and video. This has been brought about by the desire to transmit audio and images over the Internet and other mobile communications systems. This unit examines, in some detail, the methods used for coding, transmitting and storing continuous signals such as speech, music, images and video. The approach taken is to examine the theoretical aspects of signal coding and transmission, with a view to current and emerging national and international standards in this area. Thus, an understanding of industry standards is underpinned by a sound theoretical basis. Implementation on Digital Signal Processor (DSP) systems and high-level coding of algorithms is a key aspect in this regard. The unit also seeks to impart an understanding of current research problems in the digital communications field. It is thus suitable for students who may wish to undertake research and development work in this emerging field.
