You may have seen me rail against how the schools teach that inversion is t he same thing as 180 degrees out. Out of phase, by definition or etymology or whatever the f*ck at least strongly implies that THIS signal is THAT sig
Now, these two waveforms, say applied to a CRO (and ALWAYS own a CRO as lon g as you shall live) and syncing, they look the same as long as they are sy mmetrical. But we have two types of symmetrical.
Consider:
/\/\/\/\/\/\/\/\/\/\/\/\
And:
/|/|/|/|/|/|/|/|/|/|/|/|/|
Or as my Wavtek will put out:
/|_/|_/|_/|_/|_/|_/|_/|_/|
With a dead time that is half the sawtooth wave.
Now, we should all know this, it is not that hard of a concept. But how is it expressed ?
If I was the word chooser of the world, a sawtooth wave would be called "Sy mmetrical in period" but NOT "Symmetrical in polarity".
What are the proper terms for that ?
