I want a solution for branches A and B, pleaseA) Determine the primary constants, R, L, G, and C for a distortion-less line working at 300 MHz. Given that the line has characteristic impedance, Zo=750, attenuation constant a=0.12Np/m, and wave velocity, v=1.4×10 m/sB) A lossless transmission line used in a TV receiver has a capacitance of 50 pF/m and an inductance of 200 nH/m. Find the characteristic impedance for sections of a line 10 meter long and 500 m long.

For an antenna system, the transmitted and the received powers are 50 W and 25 W respectively. Calculate the path loss in dB. Assume far field condition.

A cascaded system consists of two transmission lines with different characteristic impedance, which results in reflection and standing waves. The first line has a refractive index equal to 1.1; while the second line has a dielectric constant of 2.25. If a signal traveling from the first line enters the second line at an angle of incidence equal to 30 degrees, what is the resulting angle of refraction?

As a technician, you are responsible for the construction of a 10km optical communication link between Pelonomi Hospital and National Hospital in Bloemfontein.
