Investigations of the Measurement of Noise
Abstract
Progress is reported of investigations of radio interference phenomena including the development of standards for measurements and measurement technique, comparison of various types of noise meters, and construction of a standard noise meter. A critical analysis was made of present noise meter circuits and their responses to various types of noise. In addition, studies were made to establish specifications for noise meter performance. Various instruments, calibrated with sine wave signals, read differently (as much as 1000 to 1) when they were presumably reading the field intensity from the same source. Antennas for noise meters, frequency conversion, noise detectors, calibration of the noise meter, and methods of coupling a noise meter to a source of a noise are discussed.
