1. Prepare a blank drawing paper and write the words "Mathematical Coding" in the center of the drawing paper.
2. Draw several boxes under drawing paper to indicate different coding types, such as number coding, letter coding and graphic coding.
3. Draw the corresponding coding type in each box, such as number coding drawing numbers from 0 to 9, letter coding drawing 26 English letters, and graphic coding drawing different figures.
4. Under each coding type, the corresponding coding rules or characteristics are marked, such as the sequence of number coding, the uniqueness of letter coding, and the simplicity of graphic coding.
5. Add some decorative patterns on the edge of drawing paper to make the whole handwritten newspaper look more beautiful.
Finally, write your name and date on the handwritten newspaper to show your completion.
Application of digital coding;
1, digital coding is widely used in computer field: computer programming, data transmission, encryption algorithm, etc.
2. Digital coding is widely used in the audio field: for example, PCM, MP3, AAC and other coding methods all use compression algorithms to process audio signals, so as to reduce the amount of data and maintain the sound quality.
3. Digital coding is widely used in video field: MPEG- 1, MPEG-2, MPEG-4 and other coding methods are widely used in DVD, Blu-ray Disc, digital TV and other fields.
4. Digital coding is widely used in the fields of barcodes and two-dimensional codes: barcodes and two-dimensional codes are widely used in commodities, logistics, ticketing, catering, payment and other industries. They can represent the specific codes of goods, services or information in graphic form, which is convenient for quick scanning and identification.
