Why has DC power all of a sudden become ADC?

To answer a question that was asked, and then ignored: MZL

 

Chuck, thank you.

 

Maxman,

Your question was not ignored, I simply had not seen it yet.

And when I tested Google regarding MZL, I used no other descriptor - just the acronym.

Maxman, not having a clue about what MZL stood for, I could make no contribution to your question.  I was not ignoring it, I simple had never heard of MZL.

Wasnt looking for this specifically, but as I stated before.... "Analog DC" IS a common description of DC power.

I came across this in my emails. Figured i would share it.

(I have no affiliation with the EBay seller, never met them, nor talked to them).

I didnt coin the term, nor make it up. Its been around since DC has been around.

Ed,

The rest you can do on your own.

Much ado about nothing.

There are only two forms of electrical current:  direct (DC) and alternating (AC).

Wow, I thought we had laid this thread to rest way back in February!  Why would it have been dragged back up from the deep dark depths?  PM Railfan must not have been able to let it sink into the black abyss?!?

THAT does not prove your point.  You asserted the term has been around a long time.  SHOW me.  Cite examples.  What pages on what book did Thomas Edison use it.  

If you can't do that, you've got nothing.

Can you?

And telling me that I can do the "rest" on my own is like telling me to prove your point for you.  That's not my job; it's yours.

Can you?

I see several listings (5 out of 9) for a vintage clothing boutique called "Analog" in Washington, "DC"

some listings for an analog input (any value between 0 - 5V) vesus a digital (binary) input (such as TTL logic)

a listing from "Analog" Devices, a manufacturer of semiconductors

and images of DC devices with analog versus digital displays.

 

it doesn't look like "analog DC" is a very dominate electrical term, one that is used in engineering texts, and if used describes a particular product.

 Where's that dead horse when you need it?

An analog signal can be carried with DC or AC.

A digital signal can be carried with AC or DC.

DCC is digital, DC model railroad power is not. If it's not digital, it must be analog, but a more correct way to state it would be analog <comma> DC. It's not a DCC loco, it's a DC loco. It's not a digital loco (which is sort of a Maerklin trademark), it's an analog loco. Analog DC sort of doesn't make sense and outside of train forums like this I can't say I've ever heard it or saw it stated that way in any of my engineering textbooks.

So, there you have it.  ADC, DDC, AAC, and DAC.  And, then my favorite form of hard rock electrical current...........AC/DC !   Laugh

I never replied to this thread until I was asked

The EBay user could have easily typed "DC". Maybe they read this thread.  Indifferent

This ad just randomly came to me in an email. Thought i would be kind enough to share it with those who are stuck on thinking this is my evil plot to take over the electrical world or something.

I just shared a link that shows i didnt coin the term. Its not new, and Im not the only one that uses it. No reply was needed really.
