Abstract
A tamper-resistant actuator includes a valid input, configured to deliver an input electrical current through a circuit. A high-pass filter is positioned within the circuit that degrades components of the input electrical current that are outside of a predefined current range. Components that are within the predefined current range define an output current. A transistor activates a switch when the output current from the high-pass filter is received by the transistor.
