Question 1 of 27070

Q

Which of the following best describes a pulse modulation system?

🔍 Key Concepts

• Pulse modulation versus continuous-wave (CW) transmission • Relationship between peak power and average power in pulsed transmitters (such as radar) • Duty cycle: short, high-power pulses separated by longer intervals of no transmission

💭 Think About

• In a pulsed system, is the transmitter on all the time or only for short bursts? How does that affect average power over time? • If the transmitter sends brief, very strong pulses with silent gaps between, what happens to the ratio of peak power to average power? • Which choice best matches the type of power relationship you would expect in something like a marine radar set that uses pulses?

✅ Before You Answer

• Identify which option clearly reflects short, intense pulses separated by no-transmit intervals. • Compare each choice’s description of peak vs. average power with what you’d expect from a transmitter that is OFF most of the time and ON only briefly at high power. • Eliminate any option that suggests peak power and average power are nearly the same in a system that transmits in short bursts.
