The present paper describes a work on multiple fault detection in combinational network. It is being offered exclusively from the point of view of general interest and it will provide a good theoretical background of multiple fault detection in combinational logic circuits. The paper starts with the definitions of the novel “Shannon spectra” and “Shannon coefficients” corresponding to a particular order of expansion of a Boolean function. Some novel theorems purported to be useful for multiple fault analysis are then offered. The overall study reveals that the multiple fault test sets are characterized by the Shannon coefficients of the corresponding order of expansion of the Boolean function realized by the combinational network under consideration.
