The Zfirich sunspot relative number R z series has been analysed by the cyclogram method. The amplitude and the frequency variations of the Fourier 11 yr component between 1700-1983 A.D., were determined in a continuous way. Four distinct time intervals with significantly different characteristics
A correlation analysis shows that the sunspot numbers at the peaks of the last eight solar cycles are well-correlated with the sunspot numbers in heliolatitudes 20o-40 ~ (specially in the southern hemisphere) occurring in the solar minimum years immediately preceding the solar maximum years. Among
