Web19 de out. de 2024 · Accepted Answer. This toolbox uses the convention that unit frequency is the Nyquist frequency, defined as half the sampling frequency. The cutoff frequency parameter for all basic filter design functions is normalized by the Nyquist frequency. For a system with a 1000 Hz sampling frequency, for example, 300 Hz is … 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 ...
