Web22 de fev. de 2024 · More Answers (3) Normalized frequency is a ratio of a specific frequency (e.g., the cutoff frequency for a filter) to twice the sampling frequency. For example, if the sampling frequency is 8000 Hz, and you want to filter at the 500 Hz point, then the normalized frequency would be 500/ (2*8000) = 5/160. Sign in to comment. 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 ...

It depends what you mean by "normalised"; it also depends on your software's choices. "Normalised" is a word often avoided by statistical people, because it is ambiguous as between (a) scaled or standardized (e.g. to total 1 or to mean 0 and SD 1) and (b) transformed (approximately) to normality, meaning normal or Gaussian distribution.
