This article discusses a method for calculating the combined diagnostic feature called spectral signature, based on the use of mathematical apparatus Walsh transformations for logic functions and differential logical calculus. We consider a class of devices which can be implemented in the proposed method. A method for determining the spectral signatures for discrete devices differs from the known methods of diagnosis less computational complexity and allows the implementation of a self-test in the operation of devices.
