WebFeb 1, 2011 · Father is generally considered as the head of the family. He has to take care of the basic needs of the household. Mother on the other hand takes care of the in-house functions of the home. Father takes care of the members of the family by earning income through a job. Mother on the other hand is otherwise called home maker. WebThe functions ψ and φare respectively called mother and father wavelets, and enjoy some suitable scaling and algebraic properties (see e.g. [5, 12] for a complete account on wavelet decompositions).
