If the pulse repetition frequency (PRF) is 2000 Hz, what is the pulse repetition interval (PRI)?
⢠Pulse Repetition Frequency (PRF) is how many pulses are sent each second (measured in Hertz, 1/s). ⢠Pulse Repetition Interval (PRI) is the time between pulses (measured in seconds). ⢠The mathematical relationship: PRI is the inverse of PRF.
⢠How are frequency (in Hz) and time period (in seconds) related in basic physics formulas? ⢠If a radar sends 2000 pulses every second, how much time must pass between each pulse? ⢠When you calculate the time for one pulse at 2000 Hz, does the result fall in the milliseconds or microseconds range?
⢠Write and use the formula PRI = 1 / PRF with proper units: seconds and Hertz. ⢠Carefully handle the decimal places when converting from seconds to smaller units (like milliseconds). ⢠Compare your calculated PRI value with each choice and check which one matches numerically and with correct decimal placement.
