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.
The LN2410SBC is a high performance Single board computer based on ARM920T (MMU included). Its ultra low power consumption, various built-in IO ports and support for Linux/WinCE/RTOS make it suitable for many industry applications.
