Description

Comprises an experiment board, housed within a board carrier, for use in conjunction with, and powered by the Master Unit (700020, supplied separately) teaching a practical course on digital signal processing, experiments being wired using 2 mm cables (700022, supplied separately). Attention is paid to the realisation and function of fibre optic transmission systems with emphasis on applications of PCM technology, for example the transmission of voice and signals with real telephones, sound cards and CD players. Course content, experiment instructions and tasks are taught via course-specific software.
