Correlational spectral responses invariant with noninertial one-to-one functional transformations of random processes

The paper is concerned with properties and application of concorrelational functions and conspectral power densities of stationary and stationarily related random processes $X(t)$ and $Y(t)$, or responses whose values do not change if $X(t)$ and $Y(t)$ are subjected to non-intertial one-to-one functional transformations.
