ima li neko negdi napisano ¨to je duty cycle? ili bar ovo prevedeno?

--------------------- Duty cycle is the proportion of time during which a component, device, or system is operated. The duty cycle can be expressed as a ratio or as a percentage. Suppose a disk drive operates for 1 second, then is shut off for 99 seconds, then is run for 1 second again, and so on. The drive runs for one out of 100 seconds, or 1/100 of the time, and its duty cycle is therefore 1/100, or 1 percent.

The more a circuit, machine or component is used, the sooner it will wear out. Therefore, the higher the duty cycle, the shorter the useful life, all other things being equal. If the above-mentioned disk drive has a life expectancy of 1,000,000 hours based on a 1 percent duty cycle, that same device's expectancy would probably be about 500,000 hours based on a duty cycle of 2 percent, and 2,000,000 hours based on a duty cycle of 0.5 percent.

upravo to ?to pi?e. Duty cycle je odnos izme?u duljine trajanja 1-ce i nule u pravokutnom signalu... Npr, period impulsa je 10 s a jedinica traje 0.5 s. Onda ti je duty cycle 0.5/10=0.05 ili 5%. Obi?no je taj broj izme?u 10 i 80 %.

Zdravo selja?ki, duty cycle je vrijeme pobude ure?aja prema ukupnom periodu ponavljanja tog signala. klju?no je da je signal iole sli?an pravokutnom jer jedino tako ima? uklju?eno isklju?eno podru?je.

Dana 30.09.2007. 15:49, Mate upi chelom po tipkovnici i nastade slijedeci tekst:

duty cycle je omjer trajanja impulsa u pravokutnom signalu. ako je 50%, jednako dugo ce trajat "brijeg" i "dol" pravokutnog signala (perioda je npr

2ms). ako je duty cycle 20%, onda ce "brijeg" trajat 20% vremena od ukupne periode (perioda npr 10ms, onda "brijeg" traje 2 ms)...
