wave filter
An instrument that clarifies a signal by filtering out all other noise. A wave filter is useful for receiving communications in deep space where there are other stellar phenomena that emit frequencies too. These extra frequencies become part of the white noise always present in space. A wave filter will keep a satellite from being confused by this extraneous noise.
