How wide is a square pixel on PAL TV (and/or NTSC)? I _think_ i want the answer as a number of nanoseconds (or reciprocal MHz). In other words, if i built a 1980s microcomputer with a pixel clock of H MHz (H being the rate at which successive pixels are encoded on the active portion of the horizontal scan) and a draw a circle Z by Z pixels, for what H is it actually a true circle? I know TVs differed and were adjustable, but what does the standard say?
(boost?)
