OPERATION OF HIGH-FREQUENCY AND DIGITAL-TO-ANALOG CONVERTERS BY A FIELD-PROGRAMMABLE GATE ARRAY

Abstract

The analysis of the main requirements set to the parameters of electrical stimulation signals is carried out. The biological tissue is considered as a linear system. Expressions allowing to determine the optimal parameters of electrical stimulation signals are proposed. Based on the study of the functional condition of the neuromuscular system, by using the software package LabVIEW and the created matching scheme, a system is developed for partial restoration of electrical activity of muscles. Based on the LabVIEW software package, the system allows to generate sine, triangle, sawtooth and rectangular low-frequency pulses. The results of simulation performed by using the HSPICE program are introduced.
