What is exactly the difference between the Bandwidth and the carrier frequency ? And if we have two channels with the same bandwidth but with different carrier frequency will we have different speeds ? For example :
System A : Bandwidth = 1 Khz , Carrier frequency = 1 Ghz
System B : Bandwidth = 1 Khz , Carrier frequency = 1 Mhz
If we used 16-QAM in both systems will baudrate be the same ?
