Why would one like to talk about something as if it were something that it's not?
Even if one wishes to think of a signal as the flow of charge, the send/return notion falls flat on its face, as in audio, our signals are AC, not DC, so half the time your send is a return and your return is a send.
So how does thinking in terms of send/return provide anyone with any sort of meaningful knowledge and understanding?
It doesn't. It just leads to mis
|Anyone who works with electronics will talk about it as a send/return (including my EE professors) because that is conceptually the way that is easiest to analyze.
Just because we've got into the habit of something doesn't mean the habit is a good one. And if we never question our habits, the bad ones only get more and more entrenched.
|If you want to argue semantics like that you're going to have to take on a lot more people than are present in this thread.
As a wise man once said, even a journey of a thousand miles begins with a single step.
|We pick the ground reference (usually) because it is common to the most signals, or is most easily understood that way. Feel free to just start labeling things points A and B, but you'll lose a lot of people when trying to explain things.
So instead I should tell people things which will likely only lead to misunderstanding?
