Antiresonance in magnitude and opposite in phase. The principle of antiresonance is used in wave traps, which are sometimes inserted in series with antennas of radio receivers to block the flow of alternating current at the frequency of an interfering station, while allowing other frequencies to pass. Antiresonance In the physics of coupled oscillators, antiresonance, by analogy with resonance, is a pronounced minimum in the amplitude of one oscillator at a particular frequency, accompanied by a large shift in its oscillation phase. Such frequencies are known as the system's antiresonant frequencies, and at these frequencies the oscillation amplitude can drop to
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" . Seeing one thing as something else is not the recognition of some truth or fact, and so "the attempt to give literal expression to the content of
