duty cycle[′düd·ē ‚sī·kəl] (communications) The product of the pulse duration and pulse repetition frequency of a pulse carrier, equal to the time per second that pulse power is applied. Also known as duty factor. (electronics) duty ratio (engineering) The time intervals devoted to starting, running, stopping, and idling when a device is used for intermittent duty. The ratio of working time to total time for an intermittently operating device, usually expressed as a percent. Also known as duty factor. (metallurgy) The percentage of time that current flows in equipment over a specific period during electric resistance welding. (nucleonics) The fraction of time during which a pulsed accelerator beam is on target, usually expressed as a percent. Also known as duty factor. duty cycle(1) A machine's rated capacity to continuously perform work under normal conditions. It generally applies to mechanical devices such as printers, in which case it would indicate the number of pages that can be printed per month without a problem.
(2) The ratio of a device operating versus cooling down. An 80% duty cycle means that it is capable of running 80% of a specified time period and turned off for the remainder.duty cycle
du·ty cy·cle (ti:ttot) (dū'tē sī'kĕl) The ratio of inspiratory (ti) time to total-breathing-cycle time (ttot). duty cycleDuring chest compressions of a victim of cardiac arrest, the relative amount of time that the chest is compressed compared to the time that the chest is allowed to recoil to its fully inflated position. A cycle of 50% occurs when chest compression equals chest recoil. See also: cycleFinancialSeeCycleFinancialSeedb/dc |
