MEASURING EQUIPMENTS FOR INVESTIGATIONS OF ULF-RADIATION,

Abstract

For investigations of naturally occuring electromagnetic radiation with a period of 10 sec to 15 sec the necessary equipment has been developed. In the report are described an ULF-generator with an extremely short starting time, an amplifier with an input resistance of 70 x 10 to the 9th power ohms, and equipment for a frequency transformation by means of a tape recorder.
