摘要 在对语音通话中回声产生的机理进行分析的基础上,研究了回声消除的原理。介绍了FM2010芯片的主要技术特点,并通过设计电路,结合QQ软件进行实验,运用FM2010芯片实现了回声的消除。实验结果证明了设计的实用性。 It studied the theorem of echo elimination based on the analysis of the mechanism of the arise of echo in the communication by Intemet .The main technology feature of FM2010 was introduced,then achieve the effect of echo elimination by design with FM2010. The test results proved the pragmatism.
