IPC: H03M5/20
Filed: 1980-04-28
Abstract: PURPOSE:To perform an operation in a high speed stably with high precision, by providing an integral holding circuit to eliminate degradation due to a control loop delay and by digitizing an integral value circuit, in a block integral value control system having multilevel transmission code. CONSTITUTION:Two binary code sequences supplied from input terminals 100-A and 100-B are subjected to series-parallel conversion respectively and are subjected to the parallel processing by binary-quad code converting circuits 111 and 112. These quad code sequences are integrated throughout one-block by one-block digital integrating circuit 113, and the obtained one-block digital integral value is held and is compared in polarity with the past integrated value. If they have the same polarity, the polarity bit is issued from polarity deciding circuit 16 to reverse the polarity of the binary polarity determining sequence; and if they have different polarities, the polarity is not reversed, and binary code sequences are output from output terminals 102-A and 102-B. Meanwhile, the held one-block integral value has the polarity controlled by the polarity inversion bit and is applied to the past block digital circuit.

Abstract: PURPOSE:To amplify signal line efficiently without any influence of excitation light by providing a core with the highest refractive index to a center part, a core with a low refractive index to its periphery, and a core with the lowest refractive index to its periphery. CONSTITUTION:The optical fiber is formed by providing the core 10 with the highest refractive index to the center part, the core 11 with the lower refractive index than the core 10 to its periphery, and the core 12 with the lowest refractive index to the periphery of the core 11. The core 10 transmits only single- mode light and the core 11 transmits multimode light. Then, Nd to be light- pumped is added in the core 10 and signal light L0 is admitted into the core 10 from an end surface of the fiber and transmitted. Excitation light is admitted into the core 11 from the flank of the fiber and diffracted through a grating 13 provided to the core 11 to propagate in the boundary of the core 11. The signal light L0 is amplified by Nd excited with the excitation light and guided out as output light L.
