I still have some hardbound copies of books like that. National did a bunch of linear books that are near-priceless (like the original Audio Applications books, which I still have!). Analog Devices did a bunch on converter technology too. Over the years I've shed more and more of my books and other flotsam and jetsam, but those books are likely to pass on to my son (who leaves for CalPoly this fall to study EE). In a tangental response to the OP: I have long emphasized to my son that he include a LOT of analog in his studies. We've had many a kitchen table discussion with pen and paper on the topic of opamps. Digital is nice, digital is important, but analog is the basis of everything and as digital frequencies keep going up a lot of the design rules are more analog than purely digital. I promise the more you study opamps, the more you will appreciate and respect them. It's stunning what a simple three terminal black box (OK, triangle! :)) can do. |

Think signal integrity, and understand that 10Gb/s signals are analogue :) I too have saved the NS books, and many more |

He still rolls his eyes at me when I drag him over to the oscilloscope for something, but I know data is seeping in through the cracks. ;D |
