The critical sensitivity of instruments with large relaxation times
Abstract
The paper considers instruments for which the motion of the moving systems is described by a differential equation in terms of the column vector of the output quantities and its first and second time derivatives, the column vector of the measured quantities, and the column vector of thermal noise. The coefficients include symmetric matrices of masses and stiffnesses. It is shown that instruments with large relaxation time will show greater accuracy in transient regime than in steadystate regime.
