在CELP编码器中，通常用延迟为抽样间隔整数倍的长项预测器表征浊音语音的准周期性。
The CELP Coder usually USES a long-term predictor that the delay is the integer multiples of sampling interval to exploit the quasi-periodic structure of speech.
像元结构对输入图像的抽样使联合变换功率谱和相关输出是空间周期性重复的。
The present method is achieved with an amplitude gray-scale spatial light modulator (SLM) as the image input device and based on double exposure holographic phase-shifting interferometry.
