With the development of digital communications technology, data transmit rate and the accuracy rate is getting higher and higher requirements. How to achieve high-speed digital communication systems and high-frequency carrier signal must be addressed. The development of programmable logic devices and large-capacity storage solves this issue sheds some light on. 摘要 I
