1.	What Are The Properties Of Unitary Transform?
Answer» Determinant and the Eigen VALUES of a unitary matrix have unity magnitude The ENTROPY of a random VECTOR is preserved under a unitary Transformation Since the entropy is a MEASURE of average information, this means information is preserved under a unitary transformation.
