What Does Modulated Spurious Signal Mean?
A modulated spurious signal is a carrier signal that emanates from an information processing device and can be intercepted. It is a type of compromised signal referred to in Telecommunications Electronics Material Protected from Emanating Spurious Transmissions (TEMPEST), which refers to the investigation and testing of compromising signals. These signals are generated from the modulation of carrier signals and the electromagnetic field that can be created around them.
