| Abstract: | The sunspot numbers is the major targets which describes the solar activity level,The solar activity influences human's health and human to rely for existence directly of environment-the Earth.According to digital signal processing,According to digital signal processing principle and adopting various processing methods,the analysis handled mean of year of the sunspot in 1770-1869 years.reached the conclusion on sunspot to exist11-12 year of the period.The experiments show that method to is effective studying the solar activity regulation and celestial regulation |
