Question 1 of 27070

If the RADAR unit has a pulse repetition frequency (PRF) of 2000 Hz and a pulse width of 0.05 microseconds, what is the duty cycle?

🔍 Key Concepts

• Duty cycle is the fraction of time the RADAR transmitter is actually ON during one complete cycle. • The basic formula: duty cycle = pulse width × pulse repetition frequency (PRF), but be careful with units. • 1 microsecond (µs) must be converted to seconds before multiplying by PRF in Hz.

💭 Think About

• Write the formula for duty cycle using the given pulse width and PRF, then check what units each value should be in. • Convert the pulse width from microseconds to seconds before doing the multiplication. What power of 10 is involved in that conversion? • After you compute the decimal value, compare it directly with the answer choices and see which one matches your result.

✅ Before You Answer

• Confirm that PRF in Hz means pulses per second, so its unit is 1/second. • Convert 0.05 microseconds to seconds correctly (watch the number of zeros). • After multiplying, ensure the duty cycle is a dimensionless decimal number between 0 and 1, then find the closest matching choice.
