How much time is spent scanning across each row of pixels during screen refresh on a raster system with resolution 1024*768 and refresh rate of 60 frames per second?
How much time is spent scanning across each row of pixels during screen refresh on a raster system with resolution 1024*768 and refresh rate of 60 frames per second? [5]
- Resolution: $1024 \times 768$ pixels (horizontal × vertical) - Refresh rate: $60$ frames per second Number of scan lines (rows) = vertical resolution = $768$ Time per frame (full screen refresh): $$ T{frame} = \frac{1}{\text{refresh rate}} = \frac{1}{60} \text{ s} = 0.01667 \text{ s} = 16.67 \t...
