A Modified Ultrasonic Pulse‐Echo‐Overlap Method for Determining Sound Velocities and Attenuation of Solids

The ultrasonic pulse‐echo‐overlap method described by Papadakis [J. Acoust. Soc. Amer. 42, 1045 (1967)] has been modified to permit simultaneous measurement of the time delay and the relative voltage ratio between any pair of returning echoes in the pulse‐echo train. All the components involved in the present modification are commercially available items, and this instrumentation system for the ultrasonic pulse‐echo‐overlap method is compatible with the pulse superposition method.
