CMET 437-Data Communication Methods HW2- Due in class, March 4, 2019 1) During a communication session, sending one bit takes 50 microseconds. Notice that one second is 10 microseconds. What is the transmission rate during this session? (You can write your answer in bits per second (bps) or kbps) 2) Consider a signal which has nonzero spectrum values between fl-100 Hz and f2-20000 Hz while its spectrum is zero for the frequencies less than 100 Hz and its spectrum is zero for the frequencies larger than 20000 Hz. What is the absolute bandwidth (BW) of this signal? 3) If the signal power is 10 Watt and noice power is 0.1 Watt, then what is SNR (signal to noise ration)? What is SNR in dB? 4) A channel exists between 1MHz and 5 MHz. The received signal has SN Rd value of 10 dB. What is the capacity of this channel? The answer will be stated in bps, kbps or Mbps. 5) Describe how much attenuation is experienced for different frequencies for a. Twisted pair cable b. Coaxial cable C. Optical fiber
