DEFINITION

Classification: 367/41

Transmitted correlation:

(under subclass 38) Subject matter wherein an acoustic wave emitted by the system and reflected by a discontinuity is detected and the information or intelligence therein identified by comparing the signal representative of the detected wave with a signal representative of the emitted wave.

(1) Note. In the subject matter of this subclass type and signal representative of the emitted wave may be produced by

the detector in response to the detection of waves arriving thereat directly from the transmitter.
