Question for rmarotta
Posted on 1998-06-30
Regarding top my previous question, remember that you gave me the following answer:
Are you speaking of the mark and space frequencies for frequency shift keying? (FSK)
If so, perhaps this is what you want:
2400 baud Space = 2450 Hz, Mark = 4450 Hz
1200 baud Space = 1300 Hz, Mark = 2100 Hz (Bell 202R compatible)
300 baud Space = 1070 Hz, Mark = 1270 Hz (Bell 102 compatible)
Please re-open the question if the current proposed answer has not provided a solution for
Then I'll submit this one if it is what you want.
I want to add a little question. Could you also specify the duration of the mark and space frequency. How long do the mark frequencies last and how long do the space frequencies last.
Thanks for your help
