Abstract: Decoder having modular constitution for transmission by coded pulses constituted by several identical individual modules wired up and interconnected so as to perform, in interrelation, various elementary functions of the decoding. Each of the individual modules comprises four operational amplifiers, an output amplifier, a switching device selectively connecting the output of one operational amplifier to the input of the output amplifier, and a logic control circuit responsive to coded bits to actuate the switching device.

Abstract: The invention concerns a digital coder subject to a compression law having multiple linear segments with slopes decreasing in geometrical progression having a ratio of 1/2, in which a chain of threshold detectors in a linear progression is used a first time to determine the number of the segment, then a second time to determine the position of the level on the segment.
