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.
