    • A photodiode receives an infrared signal transmitted from a transmitter. A current distributing unit outputs a detection current Id output from the photodiode as a first detection current Id1 and a second detection current Id2 to a subsequent first current-to-voltage conversion amplifier and a subsequent second current-to-voltage conversion amplifier respectively. The first and second current-to-voltage conversion amplifiers convert the detection currents into voltages with current-to-voltage conversion gains g1 and g2. The current-to-voltage conversion gains g1 and g2 of the first and second current-to-voltage conversion amplifiers are set such that ranges of signal levels in which the distributed detection currents Id1 and Id2 can significantly be amplified differ from each other.
    • 光电二极管接收从发射机发射的红外信号。 电流分配单元将从光电二极管输出的检测电流Id作为第一检测电流Id 1和第二检测电流Id2分别输出到后续的第一电流 - 电压转换放大器和随后的第二电流 - 电压转换放大器 。 第一和第二电流 - 电压转换放大器将检测电流转换成具有电流 - 电压转换增益g 1和g 2的电压。 将第一和第二电流 - 电压转换放大器的电流 - 电压转换增益g 1和g 2设置为使得分布式检测电流Id 1和Id 2可以显着放大的信号电平范围不同 彼此。

    • A discrimination circuit of the present invention checks whether a received signal is noise or a signal that is repeated with interposed rest time periods, and is provided with a low-pass filter that has a cut-off frequency that is lower than the frequency of the noise but higher than the reciprocal of a total period of one frame of the signal that is repeated with interposed rest time periods and the rest time period, and a judgment circuit that judges, according to an output of the low-pass filter, whether the received signal is noise or a signal that is repeated with interposed rest time periods. With this configuration, it is possible to discriminate between noise and a signal that is repeated with interposed rest time periods, and achieve miniaturization.
    • 本发明的识别电路检查接收到的信号是否是噪声,或者是以静止时间段重复的信号,并且具有低通滤波器,该低通滤波器的截止频率低于 噪声,但高于以静止时间段和休息时间段重复的信号的一帧的总周期的倒数,以及判断电路,根据低通滤波器的输出判断是否 接收到的信号是噪声或在插入的静止时间段中重复的信号。 利用这种配置,可以区分噪声和在静止时间段内重复的信号,并实现小型化。
