<p>SYSTEM FOR TIMING A SPORTS COMPETITION WITH TWO TIMING DEVICES The system for timing a sports competition includes a main timing device having a first time base, and a secondary timing device having a 5 second time base (5). The two timing devices are capable of operating in parallel when the timing system is enabled. The two timing devices are arranged such that the second time base (5) is synchronised by using a reference timer signal (CLKref) generated by the first time base. The second time base (5) includes a phase lock loop (10, 11, 12, 13, 14, 17) for 10 adapting the frequency of the second timer signal (CLKT2) according to the frequency of the reference timer signal (CLKref).</p> |
