Abstract: In the presented paper a method for treating a random signal bearing an information about the behaviour of a technological process is given. The main goal of the given method is to remove possible failures arising in analog sensors, which yield nonstationary behaviour of an observed signal. Then the smoothed signal is tested by a suitable test described in the paper for the regular or irregular behaviour of a technological process. One understands by the regular behaviour of a technological process that within prescribed bounds.
