<p>The invention relates to a device for the production of p lines from each of n lines, corresponding to n incident channels, provided by n transducers. Said device comprises, for each incident channel, an analogue/digital converter and p devices for the production of delays and with p adders each connected to the corresponding output from the device for production of delays. The above is characterised in comprising, for each channel, a device for commutation and correction between the output from the analogue /digital converter and the input of the p circuits for production of a delay and whereby the output of each of the p adders is connected to an interpolation device, the p interpolation devices being connected to an adder followed by a decimator.</p> |
