#148887 - Bell system teletypes Responding to: ???'s previous message |
Yea,
I used to sneak into the phone office with my father. The old card reader/teletype was the only way to get on the old Ga. Tech system. I really was thinking about a modern reason for using a current loop and at current speeds. I would only consider it for remote analog sensors at this stage of the game. Who out there is using a current loop for digital signals in a current design? |
