Abstract :
The major problems of the nondestructive inspection acoustic emission method are analyzed in the article. It was designed for generation signals special form on their frequency characteristics. The inappropriateness of the analysis method in the narrow band of frequencies is shown in the article. The development medium - Lab View 7.1, for the practical realization of the signals used by the hardware company National Instruments.
