| Abstract: | The signal generator,which can produce m sequence digital signal,was desighed by using VHDL in teaching.This signal generator is characterized with set of sequence length and feedback and can generate several m sequence signals.To complete the software design and the simulation work of the m sequence code generator,the MAX＋plus Ⅱ software of Altera Corporation was applied.Finally the hard ware downloading was tested through using the RC-EDA-IV System development board which was produced by the Beijing baikerongchuang technical limited company and the Altera corporation＇s EPM7128SLC84-15 chip of max7000s.With the digital oscilloscope observation,the production profile of m sequence code can satisfy the function request of the major technical indicators. |
