Research of special form for analysis properties in transmit channels of NDT system

摘要：

　　In this report givens descriptions of principle hardware-software complex.It was designed for generation signals special form on their frequency characteristics.Simulation of the signal occurs through the summation of harmonic components of the spectrum with user-defined step,and the registration system response reduces the measurement error value of the phase-frequency characteristic can be calculated by the algorithm to maximize the average signal power during the period of generation.Designed software and hardware system to reduce the quantity of necessary equipment for nondestructive testing by acoustic methods and to increases the flexibility of approaches to the study of a specific object.
