We are using analog signaling to transmit our data. If we utilize 4 different phase shifts and 8 different amplitudes and the bit rate is 100 Kbits/s what is the baud rate of the channel?




I was thinking that it is


log[itex]_{2}[/itex] (4 * 8)/100 =1/20




but i think it is wrong.

I'm very rusty so might be totally wrong but...

The baud rate is generally the symbol rate. If I've understood correctly you have 32 different symbols/combinations (4 * 8 = 32). So I believe the baud rate is 100,000/32.
