--notify any malfunction in the basic block and ensure switch to the reserve at the appearance of any malfunction (for example, in the case of linear amplifier, it must not notify only the defects that cause signal loss or strong attenuation of the output signal, but other possible defects such as defects which change the frequency characteristic, increasing gain or distortion, causing the system to oscillate);
