Jim brings up a very good point that most folks seem to overlook. That is "............ design seems to "only" realize some 18 or maybe 19 bits of "effective" A/D conversion as just over 100 dB dynam
Bob and Jim raise an interesting real-world aspect of A-D conversion. Perhaps a brief overview might be of interest to those encountering these concepts for the first time. Theoretically, an N-bit A/
Well they finally built a radio that's beyond understanding. I can see the new Extra Class exam: Q: What is the function of the DSP stage? 1. Makes the radio sound better 2. Everything George says ab
I would add one more line: Q: What is the function of the DSP stage? 1. Makes the radio sound better 2. Everything George says about it 3. Everything Doug says about it 4. No one knows but it sorta w
Hmmmm, ponder a comparable kind of thing regarding the triode tube sometime around 1920: "Well they finally built a radio that's beyond understanding." Q: What is the function of the TRIODE stage? 1.

Well... as well all know, this hardware and software (DSP) was developed for Military applications in the very early 70's. I remember reading my Association of Old Crows magazine back then and thinki
100db of audio differential on a signal that I want to be able to hear thru headphones should be quite enough... don't you think? CD quality sound can be obtained from 16 bits of data. I know we're
Mike, They already have, and will continue to do so inexorably. "Technology has only two degrees of freedom; forwards and down. There is no backwards." Cheers for now, 73, Adam VA7OJ/AB4OJ When are t
