Abstract: Systems and methods for detecting tampering with a pulse-producing component of an electrical device are disclosed. An example electrical device includes a pulse-producing circuit and a tamper detection circuit. The pulse-producing circuit is configured for generating at least one pulse. The pulse-producing circuit includes a pulse interface via which the at least one pulse is communicated from the pulse-producing circuit. The tamper detection circuit is electrically connected to the pulse interface. The tamper detection circuit can be connected between a pulse-counting device and the pulse interface. The tamper detection circuit is configured for communicating the pulse to the pulse-counting device via at least one electrical path in the absence of a tampering condition. The tamper detection circuit is also configured for simulating damage to the pulse interface by modifying the at least one electrical path in response to the presence of the tampering condition.
