in this paper, a method for implementing a physical model of a recirculation Converter based on the laboratory system ETS – 7000 is considered. The structure of different versions of the converters depends on the requirements for their accuracy, the bit depth of the counting circuits, the frequency and stability of the pulse generators, the resolution of the elements. The paper analyzes the hardware implementation of the recirculation Converter of time intervals in the code proposed by G. N. Abramov. This model allows in laboratory conditions to simulate processes of internal structure of the recirculation Converter, to investigate parameters of the device and features of functioning. The operation of the recirculating time – code Converter is based on the principle of regressing coincidences. In each recirculation, the pulse duration is reduced by an exemplary value of the duration, that is, the recirculation process is regressive. By counting the number of recirculations with the pulse counter from the moment of receipt of the converted time interval in the recirculator to the moment of failure of the recirculation process, it is possible to determine the duration of the converted time interval with discreteness. To implement the Converter, a standard set of logic elements is used: 7486-1 PC., 155l1-2 PCs., 155LL1 – 1 PC., as well as five 155ag1 single vibrators for signal delays on the positive and negative fronts. As a single pulse generator, a standard single-vibrator circuit based on the 155ag1 chip is used.
The presented physical model of RP allows in laboratory conditions to model processes of its internal structure, to investigate parameters of the device and features of functioning. The use of modern electronic components makes it possible to study and investigate various structures of any type of converters.
