For problems 15 and 17 A transmission line has the following per unit length parameters. R' = 0 Q/m, L' =0.4µH /m, G' = 0S /m,C' =150 pF / m Problem [15] Is this a lossless or a lossy transmission line? Problem [16] Calculate the characteristic impedance of this line at 500 MHz Problem [17] Calculate the wavelength on this line at 500 MHz

Return loss for a transmission line in terms of its reflection co efficient is given by: a) -20logl l in dB where r is the reflection coefficient. b) -10logl in dB where r is the reflection coefficient c) -10log (1/l l) in dB where coefficient r is the reflection d) -20log (1/1H) in dB where r is the reflection coefficient
