QUESTION 23 Depolarization of a transmited sigmal reduces the amount of enerpy transfer between the RFwawe and antenna. True False QUESTION 2 Given the folowing informa on determine e SNR in decibels at the rece ver transmitted power u-100 0B free space loss SU-80 dB noise [N --10 dB po erreceived P -Pf]-F5L SNR)-(P N a. [SNRF 1 70 dB . ISNRI 10 dB c [SNR-190 ua d [SNR-30dB QUESTION 25 An unguided signal can be spl into several transmission paths, with each path experiencne ctterent impediments (e.p.. reflection, scattering etc), thus causing each path to vary in length, This results in several copies ot the sienal reaching the receive at slightly difterent times, thus leading to signal distortion. This is termed muinpath fooing. True Falsn QUESTION 26 MIMO ankenna systems intencional ty takes advantage of mult ipath using spatially diversifled transmit and recee antennas, and digital signal processors (OSPs) True Falsn
