SCHEME FOR TRANSMITTING ANALOGIC SIGNALS

摘要

The scheme is applied in automation in the emission and computer equipment. It is simplified and has improved linearity and temperature stability of the emitting characteristics. The scheme maintains two phototransistor optrones (1,2), while the chain of the light-diode (3) of the first optrone (1) serves as an incoming signal. Consecutively in the collector-emitting chain of the phototransistor (4) of the first optrone (1) is connected the light-diode (5) of the second optrone (2). One of the semi-conductor transitions of the phototransistor (6) of the optrone (2) is connected to the base-emitting chain of the photo-transistor (4) of the first optrone (1).
