Can be used in front of other extenders that work better with a longer IPL (=input pulse length), notably the [[#repeater-line pulse extender\|repeater-line pulse extender]].

			: A few variations can be made of this schematic. First, it may add 1, 3 or 7 ticks to the output pulse, depending on how many of the repeaters are included, and it may omit the "instant extension" (the top slab), in which case the circuit delay is 1 tick, taken directly from the output pulse which then becomes 1 tick shorter.

			:This circuit utilizes the update order of [[Minecraft:redstone torch]]es, to generate an off-pulse with two torches that can be flipped to an on-pulse by a third torch. When the input turns on and torch 1 turns off, its prior updates only affect the top redstone wire, while the bottom redstone and torch 2 are updated later by regular updates, so torch 3 turns on after 2gt immediately before torch 2 powers it and turns off after another 2gt, outputting a 2gt pulse. There is a similar schematic in the [[#schematics-RED\|RED gallery]].

	* ~~In ''Java Edition''~~, a [[Minecraft:piston]] or sticky piston usually takes 1 tick to extend. If the activation pulse ends before the extension does, the piston or sticky piston "aborts" – it places the first of the pushed blocks at its final position (only if it's a sticky piston) and return to its retracted state instantly. This can cause sticky pistons to "drop" their block – they push a block and then return to their retracted state without pulling it back.		* {{IN\|JE}}, a [[Minecraft:piston]] or sticky piston usually takes 1 tick to extend.
