A photodiode (4) detects an intermediate frequency signal from an incoming pulse-modulated light carrier (1) and a local oscillator light beam (6) superimposed by means of a half-silvered mirror (2). The intermediate frequency (e.g. 128 MHz) is a multiple (e.g. 4 times) the modulating pulse repetition frequency (e.g. 32 MHz) which is extracted by a timing circuit (10). The intermediate frequency is divided in divider (14) by the said multiple and then phase-compared with the pulse repetition frequency in an oscillator control circuit (15) completing a phase-locked loop for the laser oscillator (5) which generates the local oscillator light beam (6). Jitter and wave form distortion problems with the regenerated pulses are thus avoided even with a significantly lower intermediate frequency than has heretofore been necessary. |

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). |

| A signalling system comprises a first data signal source (10, 14), a first data signal receiver (12, 16) and a cable 18 comprising two or more wire pairs ({1,2}, {3,6}, {4,5}, {7,8}) coupling the first data signal source to the first data signal receiver. A portion of each wire pair is wound around a magnetic core (28). A further winding (30) is wound around the core (28). A further signal source (24) is coupled to the further winding (30) and a further receiver (36, 26) is coupled to the wires to receive the further signal. The windings around the core apply the further signal to the wire pairs as a common-mode signal. This allows the further signal to be transmitted to the further receiver without affecting the signal transmitted between the source (10, 14) and the receiver (12, 16) and with only minor modification of the cable (18). | ||||||

| 본 발명은, 일반 오디오 기기나 휴대용 전화기 등에서 제공되는 오디오 또는 음성신호를 제한된 거리 내에서 디지털 방식으로 전송하고 수신할 수 있는 음성 및 음향 신호의 근거리 전송을 위한 디지털 송수신 장치에 관한 것이다. 본 발명의 음성 및 음향 신호의 근거리 전송을 위한 디지털 송수신 장치는 아날로그 형태의 입력 신호를 받아 디지털화하고 이를 비트 스트림으로 구성되는 패킷으로 재구성한 뒤, 베이스 밴드의 신호를 높은 주파수 대역으로 천이시켜 직접 전송하고 이를 수신하여 역으로 아날로그 신호로 제공하는 것을 특징으로 한다. 또한 본 발명에서의 패킷에는 해당 기기의 고유번호 또는 ID를 부가할 수 있어, 기기간 선택적인 송수신이 가능하며, 지속적인 아날로그 신호의 입력을 핑퐁(ping-pong)구조의 버퍼를 이용하여 디지털화하고 전송함으로써, 신호의 불연속을 방지하는 특징이 있으며, 실제 전송에 소요되는 시간이 입력 아날로그 신호에 대해 극히 짧은 특징이 있으므로 송수신에 필요한 전력을 극소화할 수 있는 특징이 있다. | ||||||
