The band interference
WebThe interference of two waves. When in phase, the two lower waves create constructive interference (left), resulting in a wave of added amplitude. When 180° out of phase, they create destructive interference (right), resulting in a wave of zero amplitude. In physics, interference is a phenomenon in which two coherent waves are combined by ... Webinterference, in physics, the net effect of the combination of two or more wave trains moving on intersecting or coincident paths. The effect is that of the addition of the amplitudes of the individual waves at each point affected by more than one wave. If two of the components are of the same frequency and phase (i.e., they vibrate at the same rate and are maximum …

WebWIMAX operates in the frequency band from 3.4-3.8GHz. A portion of this frequency band is within the passband of many C-Band satellite receivers. Because of this, a “standard” filter would not be able to remove the interferer as part of the interference is in the passband of the filter. Let’s suppose we have a WIMAX signal operating at 3 ...
