A mobile antenna receives two copies of the signal transmitted by the base section .The first copy is the line of sight component and the other is a reflected component
which is 20 dB weaker in terms of power than the Los component and delayed by 100 ns .If the signal is sufficiently wide band , causing constructive and destructive interference at different frequency points with in the signal bandwidth .what will be the ratio of maximum to minimum signal level varaition across bandwidth and what will be the frequency separation between two consective maxima or minima?
