<P>PROBLEM TO BE SOLVED: To determine the transmission speed of signals in a signal transmission system wherein expansion radio equipment receives a base band signal from a modulating and demodulating device and operates on the signal. <P>SOLUTION: The invention relates to the expansion radio equipment which receives a base band signal from the modulating and demodulating device and operates on the signal, including: an interface section for generating a parallel signal and a clock signal based on the base band signal; a control section for sequentially outputting signals having a different specified value which are to be compared with the clock signal generated by the interface section; and a clock circuit which determines whether the clock signal generated by the interface section coincides with each of the signals, having a different specified value, which are outputted from the control section, and outputs a coincidence signal when both the signals coincide with each other. <P>COPYRIGHT: (C)2010,JPO&INPIT |
