Ultrasonic Spectroscopy is a relatively new method to ultrasonic nondestructive evaluation. The method is based on the Fourier frequency components of an ultrasonic signal. Since most wave-materials interaction is frequency dependent, this technique proved to be more useful for quantitative studies. In this paper a general ultrasonic spectroscopy system is described and analyzed as a linear time-invarient system.
