Product Description

The 7404 is one of a range of digital communication trainers and provides all necessary inputs and connections for students to study decoding and demultiplexing of data transmitted by model 7403, the pulse code modulation transmitter. On-Board PLL provides regeneration of clock. Synchronization between transmitter and receiver is provided by pseudo random code.

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
