Pulse-compression techniques are increasingly popular in the field of Nondestructive testing. Transmitting transducers are selected primary to match bandwidth of the test signal. This is easily fulfilled in the case of classical narrowband tone burst signals, but almost impossible to fulfill in the case of broadband test signals, such as Maximum Length Sequence. Physical construction of the transducer limits its usefulness to either low or high frequencies. Frequency response contains the necessary information for selecting the best transducer. Mathematical functions, such as correlation, can be used to recover nonparametric frequency response of a measured sample. In this article is also discussed a parametric approach to estimate a transfer function based on an Output-Error model. Finally an experiment is conducted to recover sample´s frequency response using a transducer with non-ideal characteristic.
