On-Line, Real-Time Recognition System on Telegraph Codes: TETAC

This paper describes studies of the TETAC system (Teaching Equipment for Telegraph Technology Aided by Computer). The system has been developed for training students at the University of Electro-Communications. TETAC is an intelligent system which recognizes Morse code sent by hand and converts it to letters by means of online and real-time processing. In addition, the system evaluates the qualities of trainees' keying operations; namely, it identifies the students' faults or tendencies. Although TETAC is now in the testing stage, we are confident of the effectiveness of the training and of TETAC's usefulness in modernizing a maritime communication system.
