The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented.
The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940).
The design is fully pipelined for maximum throughput.

Introduction ---------------------------------------------------------
Welcome to HyperString!
One of the most significant new features with Delphi32 is long dynamic
strings. However, the built-in functions don t really exploit the full
potential of these new strings. HyperString provides over 400 fast,
efficient string management routines to help you realize the full power
of this highly versatile new data type.
