In theory, we can never extract the frequency information whose period is longer than the time window . For example, the lowest frequency is 5 Hz if the window is 200 ms. To achieve a better SNR, we would want the window to contain two or three periods of certain frequency information, which further limits the lowest frequency we extract.
