Resonator The guitar resonator is a device for driving guitar string harmonics by an electromagnetic field. This resonance effect is caused by a feedback loop and is applied to drive the fundamental tones, octaves, 5th, 3rd to an infinite sustain. Resonator A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from
Metaphor in philosophy of a metaphor, since, in his words, "much of what we are caused to notice [in a metaphor] is not propositional in character", that is to say, metaphor is a prompt to thought which cannot be reduced to or contained by a series of truth conditions . What metaphor does, Davidson maintains, is make us see one thing as something else by "making [a] literal statement that inspires or prompts the insight" .
