Intactly show receiving unit among Fig. 2, this receiving unit is made up of first branch circuit 21, second branch circuit 22 and the 3rd branch circuit 23.
First branch circuit is processed into the data that serializable transmits in order to the electric signal with sensor 20, and it comprises the amplifier 24 as input stage, and the input end 24a feedback of amplifier 24 has the electric signal from sensor 20.Sensor 20 is designed to PIN type diode, and 24 in amplifier is designed to transimpedance amplifier by the mode described in the Hewlett-Packard magazine 26-28 page or leaf in for example in Dec, 1988.The output of amplifier 24 is drawn via bandpass filter 25, and is added on the next element 26 of first branch circuit.
In the embodiment of present other elements of described first branch circuit, we suppose the light signal that light L is transmitted, thereby the electric signal that provided of sensor 20, modulate by the amplitude shift keying method.Can certainly adopt other modulation method, for example, frequency shift keying system (FSK) method, in this case, first branch circuit will be done corresponding design.
When the electric signal of FSK modulation was processed into the data of serializable transmission, signal carried out demodulation by accurate synchronous modulation method with sensor 20.For this reason, the element 26 of first branch circuit is an amplifier that is provided with the control input, and this control input also is connected to the AGC(automatic gain and controls) on the circuit 27.Be the carrier signal of reentrying, high-quality LC oscillatory circuit 28 be connected to the output terminal of amplifier 26.The output terminal of this LC oscillatory circuit 28 is connected to the control input end of agc circuit 27 by limiter 29, and 29 of limiters make the AGC control circuit of amplifier 26 form the loop.
