In this work, a new empirical mode decomposition (EMD) is introduced. It does not use extrema envelopes nor sifting procedure but the decomposition is only based on a direct calculation of its components from inflexion points. Our technique has many advantages: firstly, in contrast to the classical EMD, we give an analytical formula for the decomposition. Finally, a simulation study shows its efficiency.
