择PCB板材必须在满足设计需求和可量产性及成本中间取得平衡点。设计需求包含电气和机构这两部分。通常在设计非常高速的PCB板子(大于GHz的频率)时这材质问题会比较重要。例如，现在常用的FR-4材质，在几个GHz的频率时的介质损(dielectric loss)会对信号衰减有很大的影响，可能就不合用。就电气而言，要注意介电常数(dielectric constant)和介质损在所设计的频率是否合用。

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.
