    energy and cross corelllation

    I need answer for this question

    Q1:
    For the shown 4 signals find thier energies, cross corellation coefficients, and dimension of thier signal space.
    can you guess complete orthonomal function set

    1. How is the energy of a signal defined?

    2. How has your course defined the cross-corelation between two signals

    So you can do the first part, what about the cross correlation?
