Noise Measurements of Composition Resistors; Part I. The Method and Equipment

Voltage fluctuations due to direct current flowing in composition resistors have been measured with a National Bureau of Standards experimental test set. A second group of measurements were made as prescribed in the JAN-R-11 Specification. The two measuring systems are described and test results compared. Several groups of commercial resistors of different manufacture have been measured and the results analyzed and compared. Background theory is included.
