- An extra high voltage transmission line of length 300 km can be approximate by a lossless line having propogation constant β= 0.00127 radians per km. Then the percentage ratio of line length to wavelength will be given by ??arrow_forwardIt is desired to construct uniform transmission lines using polyethylene (εr = 2.25) as the dielectric medium. Assuming negligible losses, find the inner radius of the outer conductor (in mm) for a 76 Ω coaxial line, where the radius of the center conductor is 0.6 (mm).arrow_forwardA load has a reflection coefficient of 0.5 when referred to 50 Ω. The load is at the end of a line with a 50 Ω characteristic impedance.(a) If the line has an electrical length of 45 degrees, what is the reflection coefficient calculated at the input of the line?(b) What is the VSWR on the 50 Ω line?arrow_forward
- For the lossless transmission line shown below, the T.L. was previously charged to E=128V and the switch is closed at t=0. If Zo= 150 ohms and RL= 450 ohms, find the following VRL at t=3To VRL at t=To First reflected voltage from the load (Vr-)arrow_forwardA lossless transmission line is terminated by an open circuit. An incident signal travels from the source to the load gets reflected and travels all the way back to the source. It takes 4 microseconds for the signal to go from the source to the load and then from the load to the source. What is the length of the line (in m) if the propagation velocity is equal to the speed of light (in m/s)? Enter only the numerical value. No need for the unit. Use four decimal places (if the answer is not an integer).arrow_forwardThe impedance and propagation constant at 241 MHz for a transmission line are Z0 = 43 - j2 Ω and γ=2 + j7 m-1.
