I can tell from the thumbnail, that's just an audio power amp -- BSEE teaches all the bits you need, to understand one of those -- though perhaps leaving you to piece it together yourself, rather than, say, teaching amplifier design as its own subject.
I know several non-grads who understand amps better than a lot of "master"s, but then, I probably have two masters' worth of knowledge myself, and I'm officially only a twice bachelor's, so, take what I have to say with a grain of salt I suppose.
If you learn quickly, it won't be much trouble to understand, less than a year. Maybe a few months of directed study. If you're more average paced, you should definitely be able to work through its operation, after a BSEE curriculum. (If you aren't -- as, I'd have to guess, a modest (like ~25%?) fraction of 4-year BSEE grads can't -- well, discrete analog is probably not for you, that's one thing -- but you can probably still get good pay faking it somewhere. . . .)
