For a transmission medium, SNRdb is given as 30. If bandwith is selected as 9,07 MHz, which answer is correct? a. Bit = 3 Max Capacity = 90,80 Mbps O b. Bit = 5 Max Capacity = 81,70 Mbps O c. Bit = 5 Max Capacity = 90,70 Mbps O d. Bit = 3 Max Capacity = 92,30 Mbps O e. Bit = 7 Max Capacity = 99,90 Mbps An analog signal having frequency as 3,80 KHz is digitized with 6 bits and stored in a file. If the file size is 1,41 Mbit, which answer is correct? a. Date Rate = 45,7 Kbps Duration of the Signal = 31 minute O b. Date Rate = 26,6 Kbps Duration of the Signal = 53 minute c. Date Rate = 45,6 Kbps Duration of the Signal = 31 minute d. Date Rate = 39,3 Kbps Duration of the Signal = 38 minute e. Date Rate = 70,7 Kbps Duration of the Signal = 31 minute In a communication, the transmitted data is 1 01101011001 and the received data is 1 0 111111000 1.
