Design and construction of a two-channel data acquisition system for random processes based on FPGA

Abstract

In this work, a useful equipment for recording and analysing of random processes was developed based on field programmable gate array (FPGA). The system covers a range of different applications in the nuclear fields of study. The system is potentially applicable for zero power reactor noise analysis, time coincidence of stochastic events, dead time estimation, and probability distribution function of random processes. The designed and constructed system was tested and validated by generated pseudorandom processes. Some of the basic analysing methods of random processes were checked and verified experimentally. As the performance of the system depends on the hardware, the designed architecture is implemented on a typical system. The best performance is reported in the text.
