SYSTEM FOR SYNCHRONOUS SAMPLING AND TIME-OF-DAY CLOCKING USING AN ENCODED TIME SIGNAL

摘要

The system for synchronous sampling uses an encoded time signal, such as anIRIG-B signal. The IRIG-B signal is applied to an edge detector, whichproduces pulses based on the edges of the encoded time signal. These signalsare applied to a phase-locked-loop assembly which is arranged to produce anoutput sampling synchronization signal which is locked to the transitions inthe encoded time signal, providing a synchronous control signal for datasampling of input signals to a plurality of electronic instruments, inaddition to the use of the IRIG-B signal as time-of-day clock synchronizationfor the plurality of instruments.
