HOW DO extract input signal is first segmented into frames and EMD is conducted on every frame to extract the associated IMFs

input signal is first segmented into frames and EMD is conducted on every frame to extract the associated IMFs

Answer 1

[Wayne King]

You simply sum the intrinsic mode functions. Depending on which empirical mode decomposition routine you are using, you will obtain a matrix output with the IMFs.

One dimension of the matrix will equal the length of the input signal, simply sum the IMF matrix across the OTHER dimension.
