Introduction to Communication System How to express it with Morse code

Introduction to Communication System Expressed by Morse code as follows . Point: symbol ".", the key time is short, and the duration is one unit. Cross: symbol "-", the key takes a long time, and the duration is three units. Character interval: symbol "", the duration is three units. Word interval: symbol "/", the duration is seven units.

In fact, there are two "symbols" used to represent characters: that is, strokes and dots, or Dah and Dit respectively, or long and short. And the speed of sending the report is determined by the length of the point, and it is regarded as a reference for the time of sending the report.

Morse code is a signal code that expresses different English letters, numbers and punctuation marks through different orders. Morse code was of great importance in early radio and is a must-know for every radio communicator.

Morse code is composed of two basic signals: a short point signal "·", reading "di"; a long signal "-" that maintains a certain period of time, reading "ta". Interval: drop = 1t, tap = 3t, tick = 1t, between characters = 3t, between words = 7t.

The representation method of Morse code: In fact, there are two "symbols" used to represent characters: that is, strokes and dots, or Dah and Dit respectively, or long and short. And the speed of sending the report is determined by the length of the point, and it is regarded as a reference for the time of sending the report."-" means stroke, "." Indicate the point.

Generally speaking, any coding method that can represent written characters in a variable-length signal can be called a Morse code.

Zhang Jianwu's research field

Research direction 3: Signal processing in modern scienceIn the technical field, the application scope of electronic information system is extremely wide, mainly including communication, aerospace, radar, sonar, seismic exploration, vibration engineering and medical instruments. The degree of utilization of information determines the performance of various systems, and it is closely related to signal and information processing technology.

Professor Zhang Jianwu has been engaged in teaching and research in the field of communication, especially mobile communication and personal communication, for a long time.

Kneel down and ask for an objective and fair introduction of each major (I am a science and technology major, and I also need a literature and history)
