matlab语言实现语音信号预处理及短时加窗-Matlab language voice signal pre-processing and short-term window

本作品是由前置放大、带阻网络、数字幅频均衡和低频功率放大电路组成的数字幅频均衡功率放大器。总体方案以LM386为核心实现了前置放大功能，对放大后的输入信号通过AIC23B进行A/D采样后，用TMSC5402 DSP对采集来的信号进行处理，实现了数字幅频均衡，最后以2SC3281为核心实现了信号的低频功率放大。-This work by the pre-amplifier, band-stop networking, digital amplitude-frequency balanced and

In this paper, we propose a new method that use side view video pre-processing with DWT-SVD based water-marking scheme. This processing switch the video references of the frames with dimensions equivalent of the number of frames like width and
