<> >Finally, a note about distortion. In communication theory, the single >most beneficial reduction in distortion for a chain of amplification >is to improve the first section. Could we get some discussion on this? As I see it, if you feed an ideal signal into a section with 3% distortion, then into an ideal section, you have 3% distortion (of whatever type). If you feed an ideal signal into an ideal section, then into a section with 3% distortion, you have 3% distortion. It would seem that what you want to do is to improve wherever you get the greatest relative improvement for your bucks. [Yes, I know - there are different types of distortion, and some types tend to get reduced in processing while others get amplified or go weird on you, but let's talk first-order effects where possible.] --- "Nothing left to do but smile, smile, smile." {hao,ucbvax,allegra}!nbires!rcd -- "Nothing left to do but smile, smile, smile." {hao,ucbvax,allegra}!nbires!rcd
