Abstract
Abstract A transcutaneous nerve stimulation device and method in which trains of pulses with exponential decay-times but having fixed amplitudes, fixed widths at the time-axis and fixed repetition rates have their decay-times modulated over a series of discrete values or continuously by means of binary-counter-switched time-constant capacitors.
