Abstract:
1. A basic module that is connected to a head of n (n is a positive integer) connected expansion modules, wherein the basic module is connected to the n expansion modules, the n expansion modules performing m-time (m is a positive integer) frequency dividing to a repetitive pulse signal from a direction of the basic module to output the m-time frequency-divided repetitive pulse signal to an opposite direction to the basic module, the n expansion modules outputting frequency dividing information from the opposite direction to the basic module to the direction of the basic module, the basic module outputs the repetitive pulse signal to the expansion module that is connected adjacent to the basic module in the n connected expansion modules, the basic module obtains the frequency dividing information output from the expansion module that is connected adjacent to the basic module in the n connected expansion modules, and the basic module determines the number of connected expansion modules.
