title: [The development of a special instrument for measuring propagation velocity distribution of compound active potential using collision method].
abstract: This paper introduced a special instrument for measuring the propagation velocity distribution of compound active potential using collision method. In briefly, the principle of collision method is introduced. The structure and operation principle of the neuroelectrical amplifier, A/D converter and computer interface circuit are emphatically discussed. The instrument has the advantage of usable and low costing. It has considerable application value in clinical pathological diagnosis and research experiments of nervous system.
