🔍 Key Concepts

• Video amplifier role in a marine radar or electronic display system • What signal must ultimately control the brightness/intensity of the trace or picture on a CRT (cathode-ray tube) • Difference between position signals (X/Y or resolver) and video/intensity signals

💭 Think About

• In a CRT radar display, which signal actually turns the echo spots ‘on and off’ (bright vs dark) on the screen? • Which of the options describes a signal whose amplitude should be boosted so that it can directly control the CRT’s electron beam intensity? • Which options describe positioning or sweep functions rather than brightness/intensity information?

✅ Before You Answer

• Identify which choice corresponds to the intensity (brightness) information sent to the CRT, not the positioning information • Confirm which signals (X/Y, resolver, sweep drive) are about where the beam goes, versus which one is about how bright the beam is • Make sure the function you pick is something a video amplifier would naturally handle: amplifying a low-level video signal so it can directly control the CRT’s electron beam
