摘要： The present invention discloses a signal amplifier circuit used in, for example, a receive portion in an optical communication system, and including an automatic threshold value setting portion to automatically set a threshold value depending upon a "1" side level and a "0" side level of an input signal, an automatic gain control amplifying portion to take as inputs the input signal and the threshold value from the automatic threshold value setting portion so as to perform differential amplification, and a gain control portion to detect amplitude information of the input signal so as to feed a gain control signal according to amplitude of the input signal to the automatic gain control amplifying portion as a feedforward signal. It is thereby possible to avoid limitation of a signal amplified in the signal amplifier circuit at a time of reproduction of a pulse signal, and compensate for offsets present in circuits so as to suppress a variation in pulse width of the output signal.

摘要： An automatic threshold control circuit includes a bottom detection circuit, a relative peak detection circuit, and a voltage divider circuit. The bottom detection circuit detects an absolute minimum level of an input signal, and the relative peak detection circuit detects, in accordance with the input signal, a maximum level relative to the minimum level detected by the absolute bottom detection circuit. Further, the voltage divider circuit generates a threshold level by dividing the absolute minimum level and the relative maximum level in a predetermined ratio. Using this configuration, a signal amplifying circuit can be constructed that is capable of accurately reproducing digital signals at all times regardless of variations in the amplitude or the DC level of the input signal.

摘要： A light modulation device capable of stabilizing a phase set in phase modulation processing and improving optical communication quality. A phase modulator is provided for each of plural branched input lights and performs phase modulation of the input light. A phase shifter is provided at the upstream or downstream of the phase modulator and shifts a phase of the input light or of the phase-modulated light. A light interference section causes the output lights from the light modulator to interfere with each other to generate a multilevel phase modulated signal and interference light having a phase state different from that of the modulated signal. A monitor receives the interference light and outputs an electric signal according to the intensity. A phase shift controller generates a phase control signal based on the electric signal and applies the signal to the shifter to control the phase shift amount to be set by the shifter.

摘要： A signal detecting apparatus detects a signal received based on a current received and includes a detecting unit that detects, in the current received, a peak equal to or higher than a threshold and a time counting unit that counts a given period of time from a point in time of detection of the peak by the detecting unit. The signal detecting apparatus further includes a determining unit that determines whether the detecting unit has detected the peak again within the given period of time counted by the time counting unit. An output unit of the signal detecting apparatus outputs information indicating detection of the signal received when the determining unit determines that the peak has been detected again.

摘要： An amplifying unit performs a differential amplification with a highest level or a lowest level of an input signal and a previous input signal. A semiconductor element transfers a signal level output from the amplifying unit from a second terminal to a third terminal by using a current conducted from the second terminal to the third terminal in response to a voltage applied to a first terminal. A control unit controls the voltage applied to the first terminal of the semiconductor element based on a voltage or a current related to a reference semiconductor element. A holding unit holds a signal level output from the third terminal of the semiconductor element.
