Digital Signal Processor Implementation of Split Spectrum Processing
Scott Bailey
Advisor: Dr. T. L. Stewart

Split-Spectrum signal processing is a technique used to enhance flaw detection in the nondestructive evaluation of materials using ultrasonics. The signal processing algorithm employs a bank of filters followed by a nonlinear detector. Since the realization requires a large number of filtering operations, the objective of this project is to determine the feasibility of implementing the process using a high speed digital signal processing device. The software development and results using both simulated and actual ultrasonic data will be presented.
