Antiresonance 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 almost zero. Antiresonances are caused by destructive interference, for example between an external driving force and interaction with another oscillator. Antiresonances can occur in all types of coupled oscillator systems, including mechanical, acoustic, electromagnetic and quantum systems. They have important applications in the characterization of complex
Some Girls Are Bigger Than Others performed live only once: at the final concert by the Smiths, at Brixton Academy, London, on 12 December 1986. The performance, which included a verse ("On the shop floor, there's a calendar, as obvious as snow, as if we didn't know") not used in the studio version, was recorded and later featured as a B-side on the 12" and cassette edition of the "I Started Something I Couldn't Finish" single in November 1987. Amateur footage of the entire concert has since appeared online. In Germany, "Some Girls Are Bigger Than Others" was released as a single in slightly edited form,
