The detailed procedures of adopting filter bank property of APIT-MEMD.

(1)Generate a set of same length Gaussian white noise (m channels) (2)Add the m channels Gaussian white noise in Step 1 of APIT-MEMD to the input n-channels signal, thus (m + n)-channels signal is obtained. (3)Conducting APIT-MEMD on the resulting (m + n)-variate signal to generate (m + n)-vairate IMF groups. (4)Discarding the m-variate IMF groups from the resulting (m + n)-vairate IMG groups, the obtained n-variate IMFs can be obtained.
