(8pts) In communication system, the total time including transmission and propagation times is 110 ms. The bit rate is 4 Mbps, and the size of the file is 32 Kbytes. What is the total distance? (Consider the propagation speed to be 2.4 x 108 m/s). (8pts) We have sampled a low-pass signal with a bandwidth of 200 KHz using 1024 levels of quantization a. Calculate the bit rate of the digitized signal. b. Calculate the SNRdB for this signal
