Thus the Speed of Transmission, W, is proportional to the line speed [which is related to the number of successive current values per second you can send on the channel] AND the number of different messages you can send simultaneously. [which depends on how & what you code]
I represent the three messages simultaneously by a range of frequencies:
0 0 1… “000” = f 1
0 1 0… “010” = f 2
0 0 1… “101” = f 3
How many frequencies do I need? 2M
The resulting signal containing three simultaneous messages is a wave form changing continuously across these 8 frequencies f 1, f 2, f 3,…..
And with Fourier analysis I can tell at any time what the three different streams are doing.
And we know that the speed of transmission will vary with this “bandwidth”.
