摘要
分析了由于模拟电视和数字电视噪声产生的原因不同而导致的模拟电视和数字电视的信噪比测量的不同方法,并着重阐述了数字电视信噪比准确测量应使用的测试波形和方法。最后结合实际测试案例,探讨比较不同仪器设备的图像信噪比测试。
In this paper, the different measurement methods of analog TV signal SNR and digital TV signal SNR are intro- duced, and emphatically elaborated the waveform and methods used in the accurate measurement of Digital TV SNR. In the end, a variety of TV instruments and equipment measurement applications are discussed.
