ABSTRACT:
Apparatus (10) for processing a return waveform generated by directing an ultrasonic pulse at an object (S) under test. A signal converter (12) converts the return waveform from an analog to a digital signal. The analog-to-digital conversion rate is approximately four times the operating frequency of the ultrasonic pulse. A signal processor includes a plurality of digital signal processors (14,16,18) each of which is separately controllable to process the converted digital signal. A communications network (20) directs the analog signal, converted digital signal, and an output signal from the signal processor to a visual display (28) and to various peripheral equipment (A1,A2) connected to the apparatus. A process controller (22) controls routing of these signals to and from the signal processor over the communication network. By processing a return waveform, peak amplitude values representing flaws or imperfections in the object can be determined and the processed waveform, including peak values, displayed.
