This question is from Computer Network ) What is the bandwidth of

) What is the bandwidth of an analog signal that can be decomposed into five sine waves with frequencies at 10, 210, 100, 130 and 150 Hz? How long will it take to send a frame of 100,000 bits if the bandwidth of the digital channel is 10 kbps? What is the maximum data rate supported by this line, if the signal-to-noise ratio is 1023 with bandwidth of 10 kbps? ) What is the bit pattern of the preamble used in Ethernet frame? What is the purpose of using preamble? Ethernet requires valid frames to have at least 46 bytes data. Give reasons for choosing the minimum data size of 46 bytes. How the data of size less than 46 bytes is handled by Ethernet
