🔍 Key Concepts

• Raster scan display vs. PPI (plan position indicator) on radar screens • How television-style scanning works (lines, frames, refresh rate) • Role of clock pulses and addressing in electronic displays

💭 Think About

• Which option describes something that MUST be true for a raster scan display to work, not just something that sounds similar? • Think about whether marine radar displays actually use the same frame rate as a TV, or if their refresh is tied to antenna rotation instead. • Does a raster display need a way to know exactly which point (pixel) on the screen is being lit at each instant?

✅ Before You Answer

• Compare how a TV image is built line-by-line with how a radar raster display draws information. • Ask whether radar systems ever use raster scanning at all; if they do, that eliminates one choice immediately. • Check which statement mentions digital control (clock pulses, addressing), which is fundamental to organizing pixels in a raster.
