Further experimental research of interval overlapping method for biomedical signal measurement
Following the idea for the device development for precisely measurement of biomedical signals, the development of a computer-based instrument has begun. To design and realize the computer-based instrument for measurement of non-stationary biomedical signals, simulation model and experimental hardware solution have been developed. The overlapping interval method used in this research is based on stochastic analog-to-digital conversion, with low-resolution A/D converters and accumulation. As an example of a nonstationary signal, the electrooculography signal was used. Due to the limited speed of data transfer between the PC and the PSB, the possibility of measuring a minor number of Fourier coefficients was investigated in this paper. The results were compared with the results obtained by measuring a larger number of Fourier coefficients and by classical digital measurement. The obtained results are presented, analyzed and discussed.
