Microwave Communication When it is desired that short-range targets be clearly seen on a pulsed-radar set, it is important that the receiver and display system have A long time constant The restricted high-frequency response Low-pass filters The shortest possible time A long time constant The restricted high-frequency response Low-pass filters The shortest possible time ANSWER DOWNLOAD EXAMIANS APP
Microwave Communication The antenna separations (in meters) required for optimum operation of a space diversity system can be calculated from:where R = effective earth radius (m) and L = path length (m) S = λR/RL S = λR/L S = 3λR/L S = 2λR/L S = λR/RL S = λR/L S = 3λR/L S = 2λR/L ANSWER DOWNLOAD EXAMIANS APP
