Abstract: 1371614 Digital transmission; multi-level coding GENERAL ELECTRIC CO Ltd 8 Dec 1971 [8 Dec 1970] 58288/70 Heading H4P An arrangement providing a digit recurrence transmission frequency less than a binary information input train of the type wherein the transmitted signal has at least three possible values, i.e. levels, comprises a coder converter whereby each input word of two or more digits is represented by an output word of one or more digits. Some input words forming at least two groups are represented by two alternative output words having equal and opposite values of disparity transmitted alternately, so that no direct current component is accumulated. Preferably each output word comprises two or more digits not all of the same value so that timing information can be extracted. Each binary word received on line 4 has three bits which are coded by matrixes 1-3 into quaternary words having levels 0-3. A bistable circuit 6 determines for the translation of a first group whether the binary word results in an output having a disparity of either plus or minus two units, which are transmitted alternately: similarly bi-stable circuit 10 operates with reference to matrix 3. The cumulative disparity at any time is limited to Œ3 units. At the receiver, decoding matrix 12 reforms the original binary words and a level change detector 15 operates as a clockpulse extraction circuit. The translation code (given in the Specification) does not utilize certain words, e.g. "00" hence a detector 16 after a succession of such words provides an "out of frame" correcting signal to generator 17 to provide adjustment. An error circuit (not shown) may detect successive words with the same disparity, i.e. that alternation of such words is not being made, hence an error signal is provided. Other arrangements are described in the Specification, e.g. four bit groups are coded into 0-5 levels or two bit words may be coded into 0-6 levels. In a further embodiment six bit words may be coded into 0-3 levels. Such levels are relative and may be arranged above and below a centre zero level, i.e. Œ 1À5 units of voltage.

Abstract: 1293137 Companding encoders and decoders NIPPON ELECTRIC CO Ltd 31 Dec 1969 [31 Dec 1968] 61943/68 Heading G4H A signal decoding device for non-linearly converting a serial digital input signal containing polarity data into a decoded output signal comprises logic circuits 271-273 for converting the serial input signal into a parallel digital signal, a decode matrix 28 for converting the parallel digital signal into a non-linear parallel digital signal, a store 24 responsive to the polarity data to actuate switches 26, 311-314 for directing the input to the logic circuits and the outputs from the non-linear decode matrix through inverters 25, 301-304, and a linear decoder 32. Fig. 7 shows the device in a companding encoder provided with a P.A.M. signal input terminal 19, a sample holding circuit 20, a difference amplifier 21, a comparator 22 and a P.C.M. output terminal 23. For determining the first, i.e. the polarity bit of the P.C.M. signal, the switches 26, 311-314 are set to their "1" positions and the circuits 271-273 generate a "00" two-bit output which is converted into a "000" three-bit output by the matrix 28. A voltage terminal 29 adds a "1" bit so that the decoder 32 receives a 1000 four-bit input which it linearly decodes and compares with the output of the circuit 20. The comparator 22 receives the difference signal and if this exceeds a predetermined reference voltage a 1 bit which is the first P.C.M. digit is fed to the terminal 23 and to the store 24. If the difference signal is less than the predetermined reference voltage a "0" bit is fed to the terminal 23 and the store 24 which therefore changes over the switches 26, 311-314. Assuming the first bit to be a "1", the circuits 271-273 generate a two-bit code "10" which is converted to "100" by the matrix 28 and has a "1" bit added by the terminal 29 to become "1100" which is decoded by the decoder 32 before being compared with the output of the circuit 20 to determine the second bit of the P.C.M. signal. The third and final bit of the P.C.M. signal is determined in a similar way A companding decoder including the decoding device is also described.
