[GreenKeys] BAUD -vs- WPM

[hwhall at compuserve.com]

Been awhile since I thought about bits that much, but here goes....

Baud is not actually a word speed. A baud is the inverse of the length (time) of the shortest signal bit used on a circuit. So that may be part of the dilemma, if bauds and WPMs are only sort-of related under some conditions.

 

If I assume that all signal bits on two circuits were sent at 110 & 45.45 bauds, and that the 110 circuit was using 8 bit words and the 45.45 circuit using 6.5 bit words (5 character bits and 1.5 stop bits, one of the TTY standards if I recall correctly), and that a "word" is the same for both circuits, then we might compare word speeds like this:

(110.0 (8)) / (45.45 (6.5)) = 2.98 approx.

So, it sort of seems reasonable that the 110 circuit will get done more than twice as fast as the other.

Did I make a serious boo-boo in that thinking?

GA OMs;

OK - "Riddle Me This, Batman":

  45.45 BAUD = 60  WPM
110.00 BAUD = 100 WPM

How come, when I print the same (text/file/data), the
35-KSR (8-level ASCII) finishes WAY BEFORE the 28-KSR
(5-level Baudot) printing the same file?

True: I haven't timed the 2 beasts - but I know that
the 110 Baud machine finishes more than 2 times before
the 45.45 Baud machine does.
