What two active electronic devices are used to accurately recreate, modify, and transmit Electronic Deception signals?

The correct choice highlights the roles of repeaters and transponders in electronic warfare. Repeaters are designed to receive an incoming signal and then regenerate and retransmit it, allowing for the modification of the signal characteristics in order to create effective deception tactics. This can involve altering the signal's amplitude, frequency, or timing to create confusion for enemy systems.

Transponders, on the other hand, have the capability to respond to incoming signals with specific, pre-programmed responses. In the context of electronic deception, transponders can serve to modify and relay deceptive signals back to enemy radar or tracking systems in a way that can mislead or confuse them about the true situation.

Together, these devices enable sophisticated electronic deception strategies by allowing operators to craft and manipulate signals that misrepresent actual conditions on the battlefield, thus enhancing the effectiveness of electronic warfare operations. Their combined functionality makes them crucial for accurately creating and transmitting signals that can deceive adversaries.
