WebSine sweep was played by a good loudspeaker of which I have the FR specs. Now these FR charts have different "dB ranges": Mic FR: -90dB to -10dB. Speaker spec: starts at -45dB, moves to 85dB and stays mostly linear. The goal is to normalize the mic FR data w.r.t to the speaker's FR spec and then use that result to create an (inverse) FIR filter. Web5 de jun. de 2012 · When corpus-based studies examine the frequency of features across texts and registers, it is important to make sure that the counts are comparable. In particular, if the texts in a corpus are not all the same length, then frequency counts from those texts are not directly comparable. For example, imagine that you analyzed two texts and found ...

WebThe formula for the test is as follows: χ 2 = ∑ i j ( O i j − E i j) 2 E i j. Where O is the observed frequency, i.e. the raw freqency that we observe in our corpus, and E refers to the expected frequency, i.e., the frequency we would expect in the corpus assuming an equal distribution (no significant difference).

WebNormalized Frequency The normalized frequency, or V number, is a parameter used in optical fibers. The normalized frequency is proportional to the radius of the fiber divided by the wavelength times the square root of the difference of the squares of the maximum refractive index of the core and the refractive index of the homogeneous cladding.
