- I am designing a custom 9600 baud link using a voice channel
- with the following specs: BW: 100-5Khz S/N = 35+ dB.
-
- Are there any "rules of thumb" about choice of carrier
- freq 2K ? 3k ? What about FSK deviation? With this
- type of system how does modulation index affect performance?
-
- High speed data communications is new to me; audio & RF is my
- thing. This link would not have any error correction other than
- "parity". "Shannon's law" shows this to be practical; but I am
- at a loss for what would be optimum.
