| Abstract: | The major constituents of the electronic circuits of the optical-electronic colour sorter are the high gain, low drift operational-amplifiers, the pulse amplitude discriminator, and the delay circuits consisting of shift registers.On the basis of presenting briefly the function of the electronic circuits of the machine, this paper analyzes principally the coupling mode between the transducer and the input terminals of the pre-amplifier, the problems related with high gain, low drift characteristics, the automatic stabilized zero voltage level circuits of the pulse amplitude discriminator, and the delay circuits consisting of shift registers. The relation between the circuit parameters and the characteristics of the machine as a whole has been studied. Finally, the criterion for the selection of the circuit parameters has been proposed. |
