In what unit is pulse duration or width measured?

Seconds
Milliseconds
Nanoseconds
Hertz

The correct answer is: Nanoseconds

Pulse duration or width is the length of time a pulse lasts for, and is typically measured in units of time. While seconds and milliseconds are commonly used units of time, they are much too large to accurately measure the duration of a pulse. In contrast, nanoseconds are much smaller units of time and are commonly used to measure pulse duration. Hertz, on the other hand, is a unit of frequency and is not used to measure pulse duration. Therefore, the correct unit of measurement for pulse duration or width is in nanoseconds.
