The EQ consists of 60 items: 40 items relating to empathy and 20 control items. "On each empathy item a person can score 2, 1, or 0." [1] A 40-item version of the test containing only the relevant questions is also available, but may be less reliable in certain applications. Each item is a first-person statement which the test-taker must rate ...
where f r is the resonant frequency Δf is the resonance width or full width at half maximum (FWHM) i.e. the bandwidth over which the power of vibration is greater than half the power at the resonant frequency, ω r = 2πf r is the angular resonant frequency, and Δω is the angular half-power bandwidth. Under this definition, Q is the ...
The test was constructed by academics John D. Mayer, Peter Salovey, and David R. Caruso at Yale and the University of New Hampshire in cooperation with Multi-Health Systems Inc. The test measures emotional intelligence through a series of questions and tests the participant's ability to perceive, use, understand, and regulate emotions.
When the RIAA equalization standard was written the inherent bandwidth limitations of the recording equipment and cutting amplifier imposed their own ultimate upper limit on the pre-emphasis characteristic, so no official upper limit was included in the RIAA definition. Modern systems have far wider potential bandwidth.
The equivalent rectangular bandwidth or ERB is a measure used in psychoacoustics, which gives an approximation to the bandwidths of the filters in human hearing, using the unrealistic but convenient simplification of modeling the filters as rectangular band-pass filters, or band-stop filters, like in tailor-made notched music training (TMNMT).
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species.
Early uses of the term Nyquist frequency, such as those cited above, are all consistent with the definition presented in this article.Some later publications, including some respectable textbooks, call twice the signal bandwidth the Nyquist frequency; [6] [7] this is a distinctly minority usage, and the frequency at twice the signal bandwidth is otherwise commonly referred to as the Nyquist rate.
