Title: Digital demultiplexer for sound transmission - has separation into slow and fast rate words each with clock and write/read circuits with recombination circuit.
Inventor: PATRICE THOMAS
IPC: H04J3/06
Filed: 1992-07-03
Abstract: The time multiplexed input (Ir) passes to a channel separation circuit (101,104), which separates out the channel with digital words at a high periodicity and those with digital words at a low periodicity.
