If the pulse repetition frequency (PRF) is 2000 Hz, what is the pulse repetition interval (PRI)?

To find the pulse repetition interval (PRI) when the pulse repetition frequency (PRF) is given, the relationship between these two measures can be applied. The pulse repetition frequency is defined as the number of pulses transmitted per second. The PRI is the time interval between the transmission of consecutive pulses.

The formula to calculate PRI from PRF is:

[ \text{PRI} = \frac{1}{\text{PRF}} ]

Given a PRF of 2000 Hz, you would calculate the PRI as follows:

[ \text{PRI} = \frac{1}{2000 \text{ Hz}} ]

This yields:

[ \text{PRI} = 0.0005 \text{ seconds} ]

This value represents the time between each pulse, confirming that the correct answer is derived from applying the fundamental relationship between the frequency of pulses and the duration of each pulse cycle. Therefore, the calculated PRI of 0.0005 seconds is indeed correct and aligns with the required definition and calculation methods related to pulse repetition in the context of radar and telecommunications systems.
