A tool designed for computing the proportion of time a system is active compared to its total operational period. For example, a signal that is “on” for 10 milliseconds and “off” for 90 milliseconds within a 100-millisecond cycle has a 10% active time ratio. Such tools often accommodate diverse input formats for time units, enabling calculations involving seconds, milliseconds, or microseconds.
Calculating this active-time ratio is essential in various engineering disciplines, including electrical engineering, mechanical engineering, and software development. Understanding and controlling this ratio is crucial for efficient power management, signal processing, and system reliability. Historically, these calculations were performed manually, but dedicated software and online tools have simplified the process and improved accuracy, facilitating design optimization and troubleshooting.
