In work use of digital processing of a signal with reference to results magnetic flaw detection steel ropes is described. Digital processing can be applied or to reduction of hindrances in a signal, or for detection of presence of defect on defectogram. Depending on a scope of steel ropes probably formation of rigid requirements to speed of processing of a signal (for example, processing in a mode of real time).
For the decision of tasks in view known methods of processing of signals - wavelet-transformation and transformation of Fourier are used. In need of signal processing in a mode of real time window transformation of Fourier owing to the small time necessary for reception of results is used. Otherwise wavelet -transformation application is possible.
As a result of work the program modules realising digital processing of signals have been received. The given modules are a part of the software for flaw detector steel ropes.
