🔍 Key Concepts

• Pulse Repetition Frequency (PRF) and how often pulses are transmitted per second • Relationship between peak power, pulse width, and duty cycle • How average power is derived from peak power and duty cycle

💭 Think About

• How long is each pulse "on" compared to the total time in one second when the PRF is 400 Hz? • What fraction of a second is the transmitter actually radiating energy (this is the duty cycle)? • Once you know the duty cycle, how do you combine it with the 100 kW peak power to get an average value?

✅ Before You Answer

• Convert 1 microsecond into seconds before doing any multiplication • Be sure to multiply pulse width × PRF to find the duty cycle (dimensionless fraction) • Confirm that the final average power is much lower than the 100 kilowatt peak power and has units of watts
