Real-time analytic signal processor for ultrasonic nondestructive testing
Hilbert transform processors have been developed to improve flaw detection in parts by sensing the rate of total energy arrival. The processor operates in real time by using a single-sideband conversion technique. An upper sideband processor has been built with a transducer bandwidth of 0.5 to 20 MHz and can resolve echoes 90 ns apart. A lower sideband processor has a bandwidth of 2 to 42 MHz and can resolve echoes 60 ns apart.<>
