I'm working on improving the "pulse circuit" article on the wiki, and I'm going to be working on the pulse generator and pulse limiter sections next (don't go read them, they're bad). The article already has a good selection of rising edge detectors and pulse extenders which pulse generators and limiters might be built from, so I was thinking I'd only put commonly-used pulse generators and pulse limiters in those sections and refer readers to the other sections for more options.
So my question is: what pulse generators and pulse limiters do you find yourself using? Not what circuits do you know of, but what do you use when you need one. Ideally, include a picture and a little comment on why you use them (easy to remember, silent, cheap, whatever). If you don't want to make a picture, just describe it.
Feel free to "ditto"/"me too" other people's answers since that will help me determine usage.
I use pulse generators A and B from the pulse circuit article on the wiki, because they are easy to remember, although I have used designs C and D before as well, for different adventure map applications. I really like FVDisco's micro circuits as well.
For pulse limiters, I have never used any as listed by the wiki. I prefer monostable circuits for my uses, but I also don't mess a lot with ALU's or other computer components.
Rising-Edge 1 Tick pulse
- Cheap (That's a normal piston w/ sand on top)
- Fairly Compact
This gets used if floor space is at a premium.
Rising-Edge 1 Tick pulse
- Silent
- 1 tall
I use this one quite a bit if space permits, mainly b/c piston sounds annoy me
Inverted Rising-Edge 1 Tick Pulse
- Only way I know how to get an 'off' 1 tick pulse
Rising-Edge 4(?) Tick pulse
- Easy to remember
- Compact
- Quiet(er? than pistons)
I generally use this one when I just need to 'normalize' input signals.
FWI: To generate a 1 tick pulse, this no longer works as of 1.5 or later
Still limits a pulse, which is all I needed it to do. Plus, it is silent, somewhat compact, and easy for me to remember.
Of course, I haven't really done anything challenging enough for me to use a limiter as of late (kinda in a nasty slump), so if I ever come across a situation where I do need such a chokehold on a pulse, and mine isn't quite achieving that, I'll definitely keep some of yours in mind.

You can put a block over the output torch to short-circuit it down to 1 tick -- the output torch becomes a rapid pulsar which is only allowed to run for one clock cycle.
Also, thanks everyone for your posts so far. I've already been a little surprised by some posts, so it's a good thing I asked, rather than just going on my opinions based on what I've found useful in my own builds.
No problem. Also, not sure if these counts as a pulse generator under normal circumstances, but I do know these contraptions.
Despite the pic, this is a design that emits really rapid pulses in a short amount of time. Super simple to make, though technically it does take up a 3x3 space. Also, it kinda has a bad rep since griefers will hook up doors and pistons to it for that classic noise machine.
This kinda seems like more of a timed switch, since the amount of items you put in depends how long something stays on/stays off. If you put only one item in, it'll make pulses (not short ones, mind you). However, it is noisy as hell, and it takes up a 2x6 area. But if hooked up and loaded up right, it can replace the need to use long loops of repeaters to generate a pulse in a certain amount of time.
Clock circuits are a large enough category that they have their own article on the wiki separate from pulse circuits. I'll be tackling that after I've cleaned up pulse circuits.

here is a smaller version to one of the pulse generators that is post up above. since i don't know how to post a pic i'll try my best to describe it.
it takes 2 redstone torches 5 redstone dust and one block however it does take up a 3x3 area
r = redstone
t = torch
b = block
rt
rbr
tr
a redsone dust goes on top of the block
and here is a even more compacted one
3 blocks
2 torches
and one redstone dust
place torches one both side of the one block and place the other 2 blocks on top of the torches and a redstone dust in the center of the block with the torches on it. very simple.
So my question is: what pulse generators and pulse limiters do you find yourself using? Not what circuits do you know of, but what do you use when you need one. Ideally, include a picture and a little comment on why you use them (easy to remember, silent, cheap, whatever). If you don't want to make a picture, just describe it.

For falling edge, I use the piston cut-off one.

I'm only looking for circuits which create a single pulse (pulse generator) or circuits which shorten the length of an input pulse (pulse limiter).
Thanks!
I'm going to hold off on multi-pulse generators until I've created the pulse multiplier section, but other than that I'm pretty happy.
Thanks, all!
