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
Tendency of the rate of profit to fall their own output prices, each capitalist controls only the price and the cost of the "labour" hired by their own business (and, possibly, some other variable operating costs). In the short term, the easiest way to reduce costs is usually to cut labour costs and reduce working hours. One dispute which has never been finally resolved is whether the TRPF should be interpreted as a cyclical tendency, or as a secular long run trend. Geert Reuten from the University of Amsterdam has argued that there is evidence that Marx originally believed in a long run secular tendency, but that, later
