The operating point of a quadrature amplitude modulation QAM256 system is shown. This is a standard 8Mbps connection. At the operating point indicated on the graph with a big dot: a) In general, what is a bit error rate? 10-1, 10-2 10-3 b) Returning to this graph, how many errors happen at one second? 10-4 10-5 10-6 c) How many errors happen at one minute? 10-7L 10 20 30 40 SNR(dB) d) What is the signal to noise ratio in dB? e) What is the numerical value for the signal to noise ratio? f) If the noise level is 5micro watts, what is the signal level? BER
