摘要: 重点研究了对汉语的语调影响较大的基频和语音的谐波结构等因素.这里把经典的采样问题由低通扩展到带通,并且为了充分地利用信号的能量,提出了复信号采样的方法和正交采样的方法.并针对汉语语音的特点,给出了一些可供参考的设计参数.

Abstract: This paper emphasizes the study of the factors effecting remarkably the chinese tone, such as the basic frequency and so on. The classical smapling method is herein extended from lowband to bandpass frequency. In order to reduce the energy loss of the signal, the methods of complex and quadrature sampling of bandpass frequency are put forward. Based on the features of chinese speech some parameters available for reference are given.
