The measurement of temperatures, especially low ones, by means of the thermal noise

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

Measurements of the absolute temperature are analyzed in this paper by means of a method which enables to suppress the noise of the amplifier. The theoretical analysis is made and the relation between the time of integration and the error of this statistical measurement is derived. The RC filter is used instead of the integrator and the relation between the error of the measurement and the time constant of the filter is derived.
