Formulas:
1.
To find Baud: B = 1 sec/P, where P is length (in seconds) of one unit pulse.
2.
To find pulse length: P = 1 sec/B.
3.
To find dot frequency: Fd = 1 sec/2P.
Exercises 5 thru 8 are based on the above situation.
5.
The term baud has been internationally adopted to express the rate of teletypewriter transmission. A 100-per-
minute teletypewriter transmits at the rate of:
a.
20.0 baud.
c.
61.0 baud.
b.
45.5 baud.
d.
74.2 baud.
6.
The unit pulse length for 75 WPM transmission speed is approximately:
a.
13 ms.
c.
22 ms.
b.
18 ms.
d.
30 ms.
7.
The dot frequency of the teletypewriter signals at 100 WPM transmission speed is approximately:
a.
22 Hz.
c.
37 Hz.
b.
30 Hz.
d.
45 Hz.
8.
The length of the stop pulse at 100-WPM transmission speed is approximately:
a.
19 ms.
c.
25 ms.
b.
22 ms.
d.
31 ms.
