Pass Interference: When a player illegally hinders an eligible receiver's opportunity to catch forward pass.
Destructive Interference: When the peaks of one wave match the troughs of another, the waves interfere destructively. The amplitudes of the interfering waves cancel to give the resultant wave a lower amplitude.
Control Channel: A logic channel carrying network information rather than the actual voice or data messages transmitted over the network.
