I'm preparing a PowerPoint presentation, and need to plot a sine wave.
I can't do this by hand, so I need clip art of a simple sine wave.
Nothing fancy, just one or two complete cycles. Source anyone?


Thanks everyone for the inputs.

And the winner is: Cecil, W5DXP, for suggesting I use Excel. This let me
plot superimposed sine waves with various phase differences, exactly
what I wanted.

That may have been what you wanted but it certainly was not what you
asked for!

Google is clearly a closely guarded secret. Lots of people in groups
that I subscribe to have clearly never heard of it. The odd thing is
that it must take them longer to type their question than it would
take them to find the answer.


Google? Well, I searched Google and Bing! for nearly an hour, and found
dozens and dozens and dozens of sine waves. Unfortunately most of them
had superfluous embellishments and/or were of poor graphics quality,
making them totally unsuitable for my purposes.

I promise to try harder in future .....

OK it's overkill, but LTSpice will generate almost any waveform you want
and you can capture as a bitmap.

I'm telepathic. :-)

Somewhere out there on the internet, there's a site where you can build
(or, more accurately, 'synthesise') your own waveform from its
individual components. It's great fun and very instructive.
Unfortunately, I can't find it at the moment (but I'm looking).

Takes about 5 minutes in EXCEL.

5 mins? you've either got a very slow PC or you've set the frequency
too low :-)

Well, I had to make a fresh pot of coffee
while I was booting EXCEL. :-)

Thanks.

But what a bloody awful website! It's more or less unreadable (at least
in OE8). If I try Safari, all I get is a light blue screen, and a
message saying that I need Abobe Player 10 (and I've already got
V10.0.32.18) installed.

Nothing seems to do very much, but I'll have another look at it later
on.

But no, It's definitely not the website I was thinking about. I'm sure I
have a link to it. Will look later (after I've swept a load of leaves
up!).
