🔍 Key Concepts

• 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.

💭 Think About

• 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?

✅ Before You Answer

• 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.
