An embodiment of an assembly includes a platform (e.g., a printed circuit board (PCB)), a sensor, and a vibration-cancel circuit. The sensor is mounted to the platform and is configured to generate a sense signal that represents a vibration induced (e.g., a shock-induced vibration) in the platform. And the vibration-cancel circuit is configured to reduce or eliminate a level of the vibration in response to the sense signal. For example, such a vibration-cancel circuit is configured to reduce a magnitude of a vibration induced in platform, or to eliminate the vibration altogether, by generating, in the platform, a counter vibration that has a magnitude approximately equal to the magnitude of the induced vibration and that has a phase approximately opposite to the phase of the induced vibration. That is, the counter vibration cancels the induced vibration to reduce the net vibration that the platform experiences.
