EM PHENOMENA IN THE ELF RANGE: NATURAL BACKGROUND NOISE AND INSTRUMENTATION FOR ITS MEASUREMENT

Abstract

The report is the second of a series of three that discusses various EM phenomena in the ELF range. A general outline of the natural background noise in the frequency range between 1 and 50 cps is given and the measurement instrumentation developed and used by the EM Group is described.
