Morse code examined using modern communication theory

摘要

INTRODUCTION. We have all probably taken Morse code for granted. Undoubtedly, many of us thought that the code was just some random or ad-hoc use of DIT's and DAH's that we simply learned to achieve the Class A licence. Actually, it's a highly sophisticated and optimal code. Furthermore, when we compare it against modern analytical and highly optimised reconstructions of Morse code, the outcome would be almost exactly the same, which is testament to the quality of the original invention and why it has stood the test of time for 175 years and more. Samuel Finley Breese Morse was a most accomplished painter and a member of the Royal Academy for art. Many of his paintings are still located in the Washington, DC area of America. But it was his love and contribution to communications for which he is most remembered - Morse code. Morse devised his
