Having difficulty with the following question. I can answer parts I and II but having trouble finding a practical example.Question:Compute the maximum data rate of the following communication links;I) 4000Hz bandwidth and a signal to noise ratio(SNR) of 20dB;II) noiseless channel of 2.4GHz bandwidth with 64 signalling levels;Provide a practical communication example for each scenario.Any help would be greatly appreciated. 
Practical communication example for a data rate scenario
computer networks
4kHz bandwidth and 20dB SNR is telephone communication.2.4GHz with 64 signaling levels is WiFi with 64QAM if I understood correctly. In that case bitrate is 6 * baud.
