57. A 75 CI lines is terminated in a load of 100 C. Percentage of incident power reflected is
58. A transmission line quarter wave section is used to reject an interfering frequency of 100 MHz. Its approximate length is
59. In a particular transmission line, electromagnetic waves were found to travel with a velocity of 2.7 x 1010cm/s. Its velocity factor is
62. A certain transmission line uses a dielectric material with a dielectric strength of 2.25. The velocity of propagation of electromagnetic signal down the line would be
63. The length of a transmission line connected from the output of the transmitter to the antenna is 10m. The length of another transmission line connected from the output of the same transmitter to another antenna is 10.5 m if the signal frequency is 100 MHz, the signals reaching the two antennas will have a phase difference of
