Electromagnetic field generator for supporting, stimulating and influencing brain activity to improve sleeping and relaxation behavior has a square wave carrier signal that is modulated using a saw-wave modulation signal

摘要

Arrangement for producing alternating electromagnetic fields for supporting, stimulating and influencing brain activities, has a generator with a power driver and a transmitter coil. The generator produces a square-wave base or carrier signal that is then modulated using a variable frequency triangular or saw-wave signal that is generated with a modulation frequency generator. The transmitter coil has an air core or a non- ferromagnetic core.
