“…As mentioned in Section I, the use of the DFT on a time frame of 200 ms, when the analysed signal contains components with frequencies not integer multiple of 5 Hz, produces inaccurate results due to the spectral leakage [28]- [32]. In fact, in these cases, since the periodicity of the signal is longer than 200 ms, the portions of the signal analysed in two adjacent 200 ms time frames differ among them.…”

“…Figure 2 shows that the Hanning window's main lobe has been expanded and lowered while the side lobe has been drastically reduced. Hanning windows outperform rectangular windows in terms of decreasing leakage [14]. The analytical bandwidth widens and the frequency resolution decreases when the Hanning window's main lobe is extended.…”
