Abstract :
The use of a parameter identification procedure to detect faults in hardware used to implement a broad class of linear algorithms defined as digital filters is presented. Using the filter coefficient estimates produced by the identifier, a method of measuring the acceptability of the filtering algorithm is suggested and a numerical example is given.
