1. Express the projection of the signal  onto the signal space spanned by the basis with  and
What is the relevance of the projection error in terms of percentage of the signaling energy?
2. Let the signal
be projected onto the space spanned by the signals illustrated in the figure below. Evaluate the projection sˆ(t) and the energy of the projection error.
