In this paper, digital analyzer of diamond detector signals of ITER Vertical Neutron Camera (ITER VNC) are described, which uses digital signal processing. Digital analyzer of pulse signals is based on ADC12500PXIe (two channels, 12 bit, 500 MHz, PXI Express), which satisfies the ITER VNC requirements. In this paper, the architecture of digital signal processing unit is given. Trapezoidal digital shaper for pile-up separation and energy spectrum unit are described. In addition, structure of digital analyzer software levels are considered

Narrowband Noise

The concept of hidden correlation of noise signals is introduced. The existence of a hidden correlation between narrowband noise signals isolated simultaneously from broadband band-limited noise is theoretically proved. A method for estimating the latent correlation of narrowband noise signals has been developed and experimentally investigated. As a result of the experiment, where a time frag ent of band-limited noise, the basis of which is shot noise, is used as the studied signal, it is established: when applying the Pearson criterion, there is practically no correlation between the signal at the Central frequency and the sum of signals at mirror frequencies; when applying the proposed method for the analysis of the same signals, a strong hidden correlation is found. The proposed method is useful for researchers, engineers and metrologists engaged in digital signal processing, as well as developers of measuring instruments using a new technology for isolating a useful signal from noise – the method of mirror noise images.
