Frequency Response
A filter's amplitude (in dB) and phase response (in degrees of lead or lag) as functions of frequency presented in tabular and/or graphical form.

Frequency response describes how evenly a component responds to notes of different pitch. Ideally, a component should increase the loudness of all tones, from the highest to the lowest, by exactly the same amount. A frequency response varying no more than +/- 3 db can be considered "flat" within the given frequency limits. (The True Sound of Music - A Practical Guide to Sound Equipment for the Home)

The measured amplitude and phase response characteristics of a mechanical or electronic system with respect to frequency. (Field of Rotating Machinery Measurment, Monitoring and Analysis)
