Function Generator Waveforms
Ground_Loop:
Nearly every function generator I've ever seen has at a minimum sine, square, and triangle outputs with various modifications thereof. I have a need for sine and square fairly often, but not once have I needed triangle where nothing else would do, especially at higher frequencies. At lower frequency I can see a need for a ramp for timing or level comparison, but that's about it. Please enlighten me to any other common uses for triangle waves.
ledtester:
With a triangle wave you can produce a PWM signal where the center of the ON state stays in the same place. This could be useful for certain applications and is called "phase-correct PWM".

Thanks, I like that one.
nfmax:
Providing input to characterise a circuit with a non-linear response, such as an optocoupler. Use a scope in X/Y mode, with the X axis showing the input voltage (the triangle wave) and the Y axis the output.

I use a triangle wave to create a sweep generator by using it to frequency modulate my signal generator.
