Extracted text: Q20. i) Choose the type of cable used to for short distance subscriber loop. Justify why this cable is preferred over coaxial cable. ii) Draw the structure and label the parts of coaxial cable. iii) The equation for AM signal is given by VAM (t) = 9 sin( 2n × 1550 × 10³t) + 3 cos( 2n × 1500 × 10³t) – 3 cos(2n × 1600 × 10 t) %3D Its radiated by an antenna with a resistance of 152. a) Find the total power carried by the given AM signal. b) Calculate the power in each side band.
