PRP is expressed in which unit?

Explanation:
PRP is the interval between successive pulses, so it is a measurement of time. In practice, the pulse repetition rates encountered in many systems sit in the kilohertz range, which translates to PRP values on the order of microseconds. For example, if the pulse repetition frequency is 10 kilohertz, the PRP is 1/10,000 seconds, which equals 100 microseconds. Using microseconds keeps the numbers convenient and precise for these ranges. Seconds would make the interval feel unnecessarily large, milliseconds would be too coarse for typical PRP values, and nanoseconds would only be relevant for incredibly fast pulsing far beyond common SPI practice.
