(d) Attenuation values in dB of a 2.6/9.5 mm coaxial cable for the different frequency and distance is given as in Table Q1(d). Assume the transmission is for 15 km distance, and the power at the beginning is 250 mW. Using this 2.9/9.5 mm coaxial cable with the frequency of 10 KHz, calculate the following, Table Q1(d): Signal attenuation for 2.6/9.5 mm coaxial cable Distance dB at 1 kHz dB at 10 kHz dB at 100 kHz 1 km -3 -7 -20 10 km -30 -70 -200 15 km -45 -105 -300 20 km -60 -140 -400 (i) Signal-to-Noise Ratio (SNR). (ii) Power at the end point in mW. (iii) Power at the end point in dBm.
