SPICE

This work is dedicated to the development of a macromodel for the virtual signal simulator of adaptive acoustics, Data@Sim, based on the formal analogy method. The structure of modeling electro- acoustic processes in adaptive acoustics tasks and approaches to the unification of research on electrical and acoustic signals are presented. An algorithm for synthesizing virtual signals that accounts for temporal parameters of sound wave propagation and attenuation, as well as noise and interference effects, is proposed.

Розглянуто алгоритм чисельного інтегрування на основі різниць вищих порядків та виділено фактори, які впливають на вибір порядку методу. Запропоновано алгоритм оцінки ефективності вибору порядку методу, проведено його дослідження на тестовому наборі схем та зроблено висновки щодо методу керування обчисленнями.

The work presents an algorithm of synthesis of SPICE equivalent circuits for galvanomagnetic sensors based on Hall devices. By means of typical library elements circuits were composed in order to take into account magnetic values and sensor’s orthogonal coordinates that are not supported by SPICE. The obtained modeling results fit the results of experimental investigations and form the basis of the sensor’s calibration procedure.
