چکیده
Digital stochastic measurement method implementation is considered from signal stationarity point of view. It is shown how conceptual block diagram for digital stochastic measurement of one Fourier coefficient can be simplified and used for developing conceptual block diagram for measuring predefined set of signal harmonics. Hardware of digital stochastic measurement block interfaced to recording block. made for recording stationary signals is used also for recording EEG signal as an example of non-stationary signals. The results of simulation and experimental verification of the method implementations are presented, and the main numerical results are: experiment error of 2.50E-03V, simulation error of 1.34E-04V and theory uncertainty of 2,83E-03V, thus confirming theoretical calculation of standard measurement uncertainty of the method. Keywords-digital measurement; dither; signal stationarity; measurement uncertainty

Digital Binary Phase-shift Keyed Signal Detector
We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...
