Abstract
The digital control system of pulsed nuclear quadrupole resonance (NQR) Fourier radio spectrometer of laboratory type is developed, the main functional-algorithmic methods of which are implemented in field-programmable gate array (FPGA) Cyclone EP1C12F324. The algorithm of the proposed program and the configuration structure of the IC, created by means of the syntax of modeling the dynamic modes of logical structures on the basis of the finite state machine and functional modules, provide for the adjustment of all necessary NQR operation modes of the spectrometer and the operative control over the performance of the radiophysical experiment. The transfer of commands to the execution units of radiospectrometer at a rate of 3.15 Mbit/s is provided through a 4-bit parallel interface.
