Morphology

frequency-response + characteristic

The phrase is compositionally built: 'frequency-response' denotes how a system's response varies with frequency and 'characteristic' means a property or parameter, so the overall meaning (the property describing response vs. frequency) is directly derivable from the parts. It is technical but follows transparent lexical composition, so a B1 learner who knows 'frequency', 'response', and 'characteristic' would likely infer the meaning.

Etymology

Frequency-response characteristic comes from the picture of a machine drawing a line that shows how a device reacts to different sound pitches. Think of frequency as low and high notes, response as how the device reacts, and characteristic as the shape of that line, so the phrase means 'a graph or measure showing how a device's loudness or strength changes with frequency'.
