Abstract
The appts. includes a sawtooth voltage pulse generator (1), a sepn. stage (2) for independent and stepless adjustment of the pulse current consequent frequency and the duration of the pulse current, and a stage (3) for constant key relationships. The generator (1) output (19) is connected to the input of stage (20) for pre-amplification. The output of stage (20) is connected to stage (21) for alteration of the keying ratio and to form right angle pulses from the saw tooth pulses. Its output is connected via a two position switch (8) to a pre-amplification stage (7) for the current pulses. A feeder (6) is connected to the inputs of stages (3,20) and to the output (19) of pulse generator (1). - The circuit includes an individual changeover switch (25) which is connected to the output of stage (30) for remote electro-analgesia and also to the input of stage (21) and the regulator (29) for the pulse ket ratio. A stage (4) for the adjustment of the current pulses and stage (3) are connected to a comparator (31) and to a control unit (32) and indicator (33).
