Product Description

The 7403 is one of a range of digital communication trainers and provides all necessary inputs and connections for students to study pulse code modulation transmission techniques. A communication link can be established by using model 7404, the pulse code modulation receiver.

Experiments:

Study of pulse code modulation
Study of A/D conversion
Study of control signals and their timing
Study of time division multiplexing
Study of synchronization by pseudo random code
Study of error check codes
Three modes of operation to regenerate original signal
