Estimating efficiency of acoustic emission signal processing methods in implementation of polynomial digital filters
The article presents a method for processing an acoustic emission (AE) signal to extract information and noise components from a noisy record. The method is based on digital filtering by polynomial models. To compensate for the introduced distortions by filters, a scheme for bidirectional proces...

| Summary: | The article presents a method for processing an acoustic
emission (AE) signal to extract information and noise
components from a noisy record. The method is based
on digital filtering by polynomial models. To compensate
for the introduced distortions by filters, a scheme for bidirectional processing of the AE signal is proposed. The
operability of the filtering method for a noisy record is
analyzed, and processing is evaluated on the basis of
quantitative indicators. The evaluation results showed
that the presented filtering method provides stability to
the influencing noise and high accuracy of processing
the AE signal recording when compared with the closest
analogues. |
