The transition from analog information, in particular, in the form of visual picture, to its digital representation for the further processing is impossible without the use of analog-digital conversion. There are many effective methods and tools for analog-digital conversion nowadays. It is needed to admit the methods based on the principle of «golden ratio» with the formation of digital data in the Fibonacci codes form among them, as well as the method of transformation in the logic-time basis with the digital data formation in the form of unit codes. A feature of analog-digital conversion in the logic-time basis is the use of the method of time-pulse conversion. This conversion method is based on quantization by the unit duration τ of the input time duration of the optical signal. This paper reviews the features of analog-digital conversion in the logic-time basis, as well as the properties of unit codes, in the form of which the resulting digital signals are formed. Two types of unit codes, normal and positional, of their noise stability are analyzed. This property of unit codes allows them to be used for data transmission, state coding in control devices, content addressing in storage devices.
