Abstract
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.<>
