A method and arrangement for the mixing of low-frequency signals, which are present in the form of digital samples

摘要

Process and device of the mixture of low frequency signals transmitted by the various time to a same member convenience receiver via the connection time multiplex in the time which connects this member, and more usually process and device for placing in communication with a plurality of telephones or terminals. / p & & p & the pulses received has the same station during a same frame are added together and transmitted once per frame in the form of a pulse which sum is wrapper at the receiver member for a time equal at the time of a frame. / p & & p & the arrangement of the summation is connected on the one hand, at the output of the analog converter, 1984, 512 and, on the other hand, at the input of the circuit of the support 521, it essentially comprises an amplifier operational capabilities 523 and 524, 528, suitably connected by transistors 522, 525, 526, 527. / p & & p & the invention relates to systems time telephone.
