| Abstract: | An experimental mimic system for the digital supersonic televiewer is presented. In the system, EPROM is used to store specific television pictures as echo amplitude signals, and the echo time signal and synchronic control signals are produced by logical circuits. All signals are processed as 4PSK signals for transmission. Hence this system can replace the main function of the well logger. It can be used for the experimental study of the electrical behaviour of the televiewer logging system. It can also be used to diagnose the operating condition of measuring equipment and the picture processing system on a surface working site. |
