WebMar 22, 2024 · The frequency resolution (delta F in the first figure) equals 1/delta T (the length of time window in sec). Thus, a 500 ms time window as we choose here results in a 2 Hz frequency resolution (1/0.5 sec= 2 Hz). This means that power can be calculated for 2 Hz, 4 Hz, 6 Hz etc., as an integer number of cycles must fit in the time window. WebJul 15, 2024 · Computation of the multivariate autoregressive model.
