Electronic pulse evaluation device for controlling muscle or nerve stimulation electrodes has input stage supplying rectangular pulses to counter stage coupled to NAND gate connected to gating stage

摘要

The pulse evaluation device has an input stage with a pulse former, e.g. a Schmitt trigger, for supplying rectangular pulses to a counter stage with synchronous and asynchronous counters, coupled to a NAND gate, in turn coupled via an inverter to a gating stage, for selective triggering of the stimulation electrodes.
