Patent DE-4038405-A1 (DE)
Inventor: HEINZMANN GUSTAV DR ING
IPC: H04B1/12
Filed: 1990-12-01
Abstract: The invention relates to a process for filtering out the lower or upper sideband of a double-sideband oscillation to be assessed from a mixture of several double-sideband oscillations, the upper and/or lower sideband of which suffers interference from the upper or lower sideband of an adjacent double sideband oscillation facing it and at least partly superimposed thereon, in radio installations, especially multi-channel radio and short-wave telecommunication installations. The interfering sidebands of the double sideband oscillation are taken by upward, downward and/or multiple mixing for conversion into the opposite position into the frequency position of the sidebands subject to the interference and eliminated by addition with the opposite sign. An embodiment is shown in the circuit arrangement of fig. 6, where frequency-doubled carrier oscillations are used for conversion into the opposite position.

Title: Transmission fault recognising method for digitised low bit coded audio signal - providing data group frame on coding side with extra checking signal
Inventor: WECK CHRISTFRIED
IPC: H04L1/00
Filed: 1991-07-29
Abstract: The audio signal consists of a series of data frames, each contg. a train of data groups of variable length and a control information about the bit number in the individual groups. At the coding side each data frame is given an extra checking information about the varying position of a selected data group, or a given bit of the selected group. The varying position is described by a digit resulting from bit counting, new with each data frame. On the decoding side the appearance of the selected group, or a given bit in it, is detected in each data frame so that the read-out rated checking information is compared with the actual one, derived from the state of a counter on the decoding side. USE/ADVANTAGE - For transmission of digitised audio signals with low bit coding, with high reliability for recognising transmission faults without any upwards limit.
