Uses for a 5 Hz frequency?

Hey, been asked to suggest a use for a 5 Hz frequency in my electronics class, i thought a strobe light? any other ideas much apreciated!!!

Brown noise

Doesn't exist.

seriously? is that really the frequency of brown noise?

Some wireless mice use 5ghz for there waves - this is the same yea?

Yes, but it can only be played on the recorder.

PK!

Sure it's the same

pssst you wanna buy a 5Hz CPU off me, it's just as fast as a 5GHz one

Significantly different.

5Hz is 5 oscillations per second.
5GHz is 5,000,000,000 oscillations per second

And there's no such thing as brown noise.

Some kind of morse code data transmission?

...as proved by Muthbusters.

...brown noise? Well, what's the average frequency of the audible component of a flatulent emission?

Flashing an LED at 5Hz.

Producing a 5Hz "tone".

Polling a sensor at 5Hz.

erm...

Can't you make people feel really uneasy with sounds of such a low frequency? Samhain is just a few days away.

If you're referring to brown noise, then nope. Can't be done.

First thing that comes to mind is communicating with submarines.

Or perhaps a rampant rabbit on low speed pulse setting.

What kind of waveform are we dealing with here?, sine, square or sawtooth?

Er, it's electronics, not sound generation. 5Hz = on and off 5 times a second. You can't have anything in between

I'd second a strobe light. Can't think of much else you could use it for, unless you wanted to make something vibrate

BloodyL · 28 Oct 2009 at 14:27

Ah, my bad, I thought we were dealing with audio waveforms, sorry.

PhillyDee · 28 Oct 2009 at 14:32

How about as a vibration for game pads, sorting items by size over a mesh, to control a motor on an egg beater, or is it nothing like that?

Er, all those waveforms are equally relevant to electronics are they not.
