Background. The issues of synthesis and correction of input and output electrical and acoustic signals in radiation-reception systems intended for acoustic non-destructive testing are considered. The aim of the work is to formalize and algorithmize the process and principles of developing new and improving existing acoustic non-destructive testing systems based on the synthesis and correction of acoustic signals in emission-reception systems. Materials and methods. An approach based on two types of signal correction in the emission-reception system is presented: constructive correction and correction of input electrical signals. The novelty of the approach lies in the algorithm for choosing a specific correction algorithm that best suits the tasks of developers of piezoelectric transducers, which makes it possible to achieve the creation of emission-reception systems with predetermined parameters of acoustic signals. Results. A generalized block diagram is presented that describes the algorithm for calculating and designing of piezoelectric transducers. This article is the first in a series of works devoted to the synthesis and correction of input and output electrical and acoustic signals in radiation-reception systems. In the following parts, the legitimacy of applying the correction of acoustic signals will be disclosed and confirmed.
