摘要： An amplifier 11 to which transistors 13 and 14 functioning as variable resistors are connected in parallel is used. A burst signal is received by a light receiving element 10 and the received signal is converted into an input current signal Iin. The input current signal Iin is converted in the amplifier 11 into an output voltage Vo. Determination is made in a determining circuit 20 as to whether the output voltage Vo exceeds a current voltage V1 which is a threshold. The result of determination is stored in a register circuit 15. Based on the result of determination outputted from the register circuit 15, a desired voltage is selected from among a number of voltages generated beforehand in a control voltage generating circuit. The selected voltage is used to generate a control voltage Vg1 or Vg2 to be applied to the transistors 13 and 14; and the generated control voltage Vg1 or Vg2 is inputted to the transistor 13 or 14 of the amplifier 11.

摘要： A binaural four-channel stereophony comprises at least two dummy heads each provided with microphones at the ears of the dummy to pick up signals from various sound sources or groups of sound sources. The binaural signals representing each sound source or a group of sound sources are coupled to an acoustic crosstalk cancellation circuit and eventually applied to two front or two rear loudspeakers. Each sound source or group of sound sources is localized between adjacent ones of the four speakers to simulate the binaural effect produced in a closed-circuit type binaural sound reproducing system.
