Definition
The Hilbert transform is used to generate a complex signal from a real signal. The Hilbert transform is characterized by the impulse response:
The Hilbert Transform of a function x(t) is the convolution of x(t) with the function h(t), above. The Hilbert Transform is defined as such:
Hilbert Transform
We use the notation to denote the Hilbert transformation of x(t).
