Abstract
Abstract The present invention relates to a device for transmitting stochastically coded information, comprising a digital multiplexer and demultiplexer connected by a series transmission line and each controlled by addressing means, the addressing means of the multiplexer and the addressing means of the demultiplexer themselves being controlled by a common random noise generator of probability equal to 0.5.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
A device for transmitting stochastically coded information comprising: a digital multiplexer with n inputs, each of which is adapted to receive one of n stochastic input signals, and a multiplexer output; multiplexer addressing means for controlling the passage of said stochastic input signals between said inputs and said multiplexer output; a digital demultiplexer with a demultiplexer input and n outputs, at each of which one of n stochastic output signals appears; connecting means between said multiplexer output and said demultiplexer input; demultiplexer addressing means for controlling the passage of stochastic signals between said demultiplexer input and said outputs; and a first random noise generator with a probability equal to 0.5 simultaneously controlling said multiplexer addressing means and said demultiplexer addressing means, whereby each of said n stochastic output signals has an amplitude which is 1/n times that of the corresponding input signal.
Claim 2
Independent Claim
142 words
A device for transmitting stochastically coded information comprising: a digital multiplexer with n inputs, each of which is adapted to receive one of n stochastic input signals, and a multiplexer output; multiplexer addressing means for controlling the passage of said stochastic input signals between said inputs and said multiplexer output; a digital demultiplexer with a demultiplexer input and n outputs, at each of which one of n stochastic output signals appears; connecting means between said multiplexer output and said demultiplexer input; demultiplexer addressing means for controlling the passage of stochastic signals between said demultiplexer input and said outputs; and a first random noise generator with a probability equal to 0.5 simultaneously controlling said multiplexer addressing means and said demultiplexer addressing means, whereby each of said n stochastic output signals has an amplitude which is 1/n times that of the corresponding input signal.
Claim 3
Dependent Claim
14 words
A device as claimed in claim 1, wherein the addressing means are shift registers.
Claim 4
Dependent Claim
47 words
A device as claimed in claim 1, in which the information to be transmitted is stochastically coded by means of another noise generator, wherein the frequency of this other noise generator is adjusted to compensate for the loss of amplitude of the information, resulting from the transmission.
