WebMar 24, 2024 · Inner Product. An inner product is a generalization of the dot product. In a vector space, it is a way to multiply vectors together, with the result of this multiplication being a scalar . More precisely, for a real vector space, an inner product satisfies the following four properties. Let , , and be vectors and be a scalar, then: 1. . 2. . 3. . • The sum of two PR functions is PR. • The composition of two PR functions is PR. In particular, if Z(s) is PR, then so are 1/Z(s) and Z(1/s). • All the zeros and poles of a PR function are in the left half plane or on its boundary of the imaginary axis. WebProperties of Positive Real Functions Positive real functions have a number of significant characteristics, which are stated below: F(v) should have Hurwitz polynomials in the numerator and denominator. The degree of the numerator of F(v) cannot be more than one greater than the degree of the denominator. bridal veil grass around tree
