[Geek 2.0]

Okay, for the sake of education (and that I've exhausted the extent of Wikipedia's ability to have a page on every minuscule topic) could someone please give a better definition of locked antiphase? I understand that it's using a PWM where a 50% duty cycle is brake, 100% is full forward, 75% half, 25% half reverse, etc. But maybe an illustration or something to that effect? I'm kinda swimming in all these terms...

Also high chop frequency. I have only a very slight idea of what that is, and how it affects Victors and Jaguars differently.

Thanks!
