24 Communication system EP86200789.5 1986-05-05 EP0201971A3 1989-02-08 James, Michael David; Andrew, Derek

A communication system comprises a plurality of subscriber stations (51-1 to 51-n) each of which comprise a transmitter (3) and a receiver (4). A switching network comprising a selection switch (57) and a synchronous digital switching network (60) is connected to the subscriber stations (51-1 to 51-n) via separating and combining circuits (52-1 to 52-n) each of which comprise a transmitter (3) a receiver (4) and an interface unit (55)

The transmitter (3) transmits a signal comprising a square wave frequency modulated signal which is modulated by a wideband (video) signal, on transitions of which short or long pulses are initiated in response to a data signal. The wideband and data signals are separated in the separating and combining circuits (52-1 to 52-n) to enable the wideband and data signals to be separately processed in the switching networks (57,60).

28 Output device JP1869583 1983-02-07 JPS59144230A 1984-08-18 HARUHARA FUSHIAKI; TOYODA MIKIO
PURPOSE:To perform proper processing when an error occurs by outputting data right before the error occurrence when receiving data has the error and updating output data when the receive data is ceased within a specific time. CONSTITUTION:When no error occurs in the receive signal, an error decision is error generation NO (GO) and a CPU5 performs output processing after fetch processing. If the error occurs to the receiving signal, the error decision is error generation YES (NO GO) and an error frequency decision is NO because of the 1st time, so the CPU5 output data right before the error occurrence after the fetch processing. When the occurrence of the error stops within the specific time after the error occurrence, the error decision is error generation NO and the CPU5 restarts normal output processing after the fetch processing to update the output data. Consequently, proper processing is performed when an error occurs.
29 Code communication system JP1050380 1980-01-30 JPS56107307A 1981-08-26 OKAMURA SHIROU
PURPOSE:To enable excellent reception, by producing a wave close to the AM wave of complement train of PCM wave, to the AM wave of PCM wave, and by making synthesized AM demodulation for both the AM waves. CONSTITUTION:A reception input 30 in separated into PCM wave and PCM at an amplitude separator 31, and the PCM wave reproduces the 1st signal S1 at a DA converter 32. The PCM wave is in AM demodulation via a processor 33 including one-bit delay, as required and again enters an amplitude modulator 34. The carrier input for the amplitude modulator 34 used the train in complement of the PCM wave of output of the amplitude separator 31. The synthesizer 36 synthesizes the PAM output of the amplitude separator 31 and that of the amplitude modulator 34, and the 2nd signal S2 is reproduced through PAM demodulation at the amplitude demodulator 37 in the PAM wave train. With the constitution, excellent reception almost without distortion can be obtained.

31 Data trasmission system JP7245178 1978-06-15 JPS54162920A 1979-12-25 UEDA SHIGEHIKO
PURPOSE:To secure the transmission of one data with one modulated pulse by applying simultaneously both the modulation of the time axis direction and the modulation of the voltage axis direction of the pulse to the pulse-encoded data signal. CONSTITUTION:Both the modulation of the direction of pulse time axis t, i.e., the modulation of the pulse duration or phase and the modulation of the direction of the voltage axis, i.e., the amplitude modulation are applied simultaneously to pulse-encoded data signal A. Thus, in case character A, for example, is transmitted, E1 and T1 pulses are selected. In the same way, E2 and T2 pulses and E3 and T3 pulses are selected in the case of transmission of character B and X respectively. In such way, the signal contents is decided for each pulse with the regularity secured previously at both the transmitter and receiver sides. As a result, each pulse can be transmitted with the fixed signal contents each. The 5-value pulse duration modulation of T1-T5 is given to the direction of time axis t, and the pulse duration modulation of the value of E1-E7 is given to the direction of voltage axis V. Thus, 35 types of data are obtained.
