【摘要】 在计算机视频信号截获中，对信号的检测是一项十分重要的任务。在信号检测中采用软件滤波的方法，既简便有高效率。本文主要讲述计算机视频还原中，对信号检测信噪比提升的研究和应用，研究了视频信号的特征和干扰噪声类型，针对干扰的特点设计应用了基于软件滤波的梳状滤波器，对检波后信号进行梳状滤波，并有效的提高了信号的信息识别度。更多还原

【Abstract】 IIn interception of the computer video signal, the signal detection is a very important task. The signal detection method using software filtering, is both simple and high efficiency. This paper This paper studies ways to improve signal to noise ratio for signal detection In computer video reduction the characteristics of the video signal and interference noise type, researches the characteristics of the video signal and interference noise type. On the basis of software filtering, This article ilteres the received signal using soft-comb filter for the signal detection. And effectively improves the signal information identification degree更多还原
