Which outcome primarily causes signal fading along a waveguide within a phased array antenna system?

💡 Explanation

Intermodal dispersion broadens pulses as they travel because different modes propagate at different velocities, therefore increasing signal attenuation rather than impedance mismatch or atmospheric conditions which affect free-space propagation.

• Which consequence results when a positive feedback loop occurs within a proportional hydraulic reducing valve?
• Which risk dramatically increases when capacitor bank switching causes repeated overcurrents?
• Which risk increases when inductive load current exceeds breaker rating?
• Which failure causes concrete spalling due to rebar corrosion?
• Which outcome occurs when differential settlement induces unintended eccentricity in a reinforced concrete column?
• Which outcome occurs when the fluid viscosity falls below threshold in a hydraulic system utilizing spool valve flow control?
