Impulse response filter

Impulse response filters are components of several Federation systems.

In 2373, Neelix told B'Elanna Torres that he had some questions about USS Voyager's impulse response filters, but she was too busy to answer them. 

Also that year, a Pah-wraith inhabiting Keiko had Miles O'Brien recalibrate and sequence the impulse response filters in Deep Space 9's subspace communication emitters, for use against the Prophets. 

In late 2375, Chief O'Brien used the impulse response filter to compensate for an inequality in the torque buffers of the USS Defiant (2375).
