Resonator 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 a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones. Another example is quartz crystals used in electronic devices such as radio transmitters and quartz watches to produce oscillations of very precise frequency. A cavity
Tendency of the rate of profit to fall tenuous, and that "Marx analyzed capitalism in its "ideal average," at a high level of abstraction. This "ideal average" can serve as a guide to examining the societies in which we live... but the two are not the same, something the disciples of the "tendency of the rate of profit to fall" school do not seem to grasp." The socialist journal Monthly Review with which Yates is associated hosted a special debate about the falling rate of profit and crisis theory, featuring Michael Heinrich, Shane Mage, Fred Moseley, Michael Roberts and Guglielmo Carchedi. Michael Heinrich argued that there is now
