I like this question, I issue has been that it seems like every "learning electronics" starts with explaining passive components, explaining semiconductors, typically over half is just theory...
You want a book with exercises that gets you to putting scope to use, right?
I am the same spot. book-wise
,
1.) Art of Electronics I have been jumping to chapter 9? or 11? on PLLs and oscillators. there is also a companion workbook.
2.)I found Malvino towards the last chapters handy for bread boarding transistor and FET circuits. (someone really complained about this book on an Amazon review. the person said he wanted to learn about IC's not the "old stuff" I really disagree thinking about it. look at the datasheet for any IC and you have passives, semi's and transistors inside that chip. To learn transistors well, means ya really get what the IC is doing...IMO
3.) i have recently found a used copy of David Terrell's book, OP AMPS, Design,..something, something. the entire book is the 741 Op AMP and it's many companions. Explanation, actual circuit builds, then math and then (brief) theory and the math to predict what you have created...All the circuit builds have oscilloscope screenshots and how/why the scope settings.
There is sooo much out there.. YouTube search for anything has always pulled up an assortment of solutions AND exercises. too
Regarding finding PDF's I print out the pages of interest,hot glue bind it (like a paper back)
This is working for me.
