Short Content: The abstract IRIG code is one kind of general international standard transmission code, widely applies between the common time-base signal equipment's time correspondence. This clock design uses the micro controller, carries on the frequency measurement based on the GPS clock signal to the local crystal oscillator, and controls the IRIG time code according to the measurement result real-time time unit's match counting value the output; Simultaneously the micro controller interior establishes a real-time temperature frequency meter, supplies in the GPS ...

Short Content: 0 introductions Along with the radio technology's development and the popularization, "the frequency " already became the physical quantity which the general populations are familiar with. But monolithic integrated circuit's appearance, was to includes the frequency measurement each kind of measuring technique to bring many significant leaps, however, the small volume, moderately-priced, the function strong and so on superiority also held the very important status in the electronic domain. Therefore. This article has given one kind take the monolithic integrated ...
