Hilbert Transform Functions

The functions described in this section compute a discrete-time analytic signal from a real data sequence using the Hilbert transform. The analytic signal is a complex signal whose real part is a replica of the original data, and imaginary part contains the Hilbert transform. That is, the imaginary part is a version of the original real data with a 90 degrees phase shift. The Hilbert transformed data have the same amplitude and frequency content as the original real data, plus the additional phase information.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
