The LPFTs of the third order PPS with a = 2.5. (a) The second order LPFT without overlap, (b) the second order LPFT with the maximum overlap, (c) the second order LPFT without overlap and with a shorter window, and (d) the third order LPFT without overlap. The window length for (a) and (b) is 1/4 of signal length and that for (c) and (d) is 1/8 of signal length.
