Aim:To explore the possibility of the low energy em ission therapy (L EET) as a physical therapeutic method for insomnia. Methods:The DSB- signal is produced in a circuit that is composed of a single chip VCO(MC16 48) ,a single chip function generater (MC 80 38) and a single chip analog m ultiplicator (MC 1496 ) and gives its output through a L C resonance circuit. Results:A kind of applicable circuit for the production of AM- signal in the sleeping- inducer was developed.Conclusion:This circuit is characteristic of its simple in structure,stable in outputand easy in adjustment.Moreover,it can be used not only in sleeping- inducer but also in the cases where AM- signal is needed
