Figure 5.

Frequency response of the non‐artifact terms for SWC (10) and ASWC (12). The two plots were built for the corresponding nominal values (a) for SWC h_SWC = 100 s the first zeroed frequency corresponding to 0.01 Hz. Correlation variations with this frequency cannot be resolved. (b) For ASWC h_ASWC = 44 s and g_ASWC = 50 s, the first zero frequency is determined by the largest parameter between h_ASWC and g_ASWC which in this case is g_ASWC = 50 s. The frequency 0.01 Hz is not zeroed and within the first lobe resulting in a better frequency resolution. At the same time, ASWC exhibit a higher suppression of side lobes [Color figure can be viewed at http://wileyonlinelibrary.com]
