The lower section of the pulse, used mainly for picture blanking during line \ufb02yback, is 12 \u03bcs wide and embraces the entire line blanking period. The narrow superimposed pulse on its top is used for gating during the period of the colour burst, and is about 3 \u03bcs wide; these line-rate pulses are separated by slicers within the chip. In some TV designs the sandcastle pulse has a component at \ufb01eld rate too, used for picture blanking and for extinguishing the scanning beams in the event of a loss of vertical de\ufb02ection: it prevents burning of the screen phosphors.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>SANDCASTLE PULSE The decoder ICs shown in Figs 7.7 and 7.9 both use a sandcastle pulse for timing and gating purposes.
