Chapter 8 Bounded Linear Operators on a Hilbert Space
8.2 The dual of a Hilbert space A linear functional on a complex Hilbert space H is a linear map from H to C. A linear functional ’ is bounded, or continuous, if there exists a constant M such that j’(x)j Mkxk for all x 2 H: (8.3) The dual of a Hilbert space 191 The norm of a …

The Hilbert transform of x(t) will be denoted by ˆx(t) and its Fourier transform by Xˆ(ω). The Hilbert transform is defined by the integral xˆ(t) = x(t)∗ 1 πt = 1 π Z ∞ −∞ x(τ ...
