🔍 Key Concepts

• Marine radar display chain – know what the video amplifier does with echoes before they go to the display (PPI scope, raster screen, etc.) • Difference between video signals (echo information drawn on screen) and control/positioning signals (used to rotate/position the sweep) • What range rings are and how they are superimposed on the display (are they ‘video’ or ‘control’?)

💭 Think About

• Ask yourself: Which of these options actually carries echo strength information that needs to be amplified before display? • Which item is associated with bearing/angle information rather than brightness/echo information? • For each choice, decide: Is this something that would be ‘drawn’ as brightness on the screen, or something that helps the radar know where to draw things?

✅ Before You Answer

• Identify which signals are truly video-type inputs to be amplified (echoes, rings, etc.). • Identify which signal is more related to antenna position / bearing (angle) than to brightness of the trace. • Before picking an answer, be sure you can explain to yourself what a resolver signal does in a radar system and whether it carries echo intensity or positional information.
