What term describes the product of pulse width and pulse-repetition frequency?

The term that describes the product of pulse width and pulse-repetition frequency is known as the duty cycle. The duty cycle is defined as the fraction of one period in which a signal or system is active. It is a crucial concept in understanding how often a specific signal is transmitted relative to the total time of the transmission cycle.

In practical applications, if the pulse width is measured in seconds and the pulse-repetition frequency is measured in hertz (cycles per second), multiplying these two values gives a measure of the time the signal is active within a complete cycle. This information is vital in various fields, including communications and signal processing, as it impacts how effectively a system can transmit information and how much energy it consumes.

Understanding the duty cycle helps technicians design and analyze systems, ensuring proper functionality and efficiency.
