本文研究了在直角或极坐标系建立测试ＨＤＴＶ图像质量用多种测试图、卡之数学模型的原理和方法；定量分析了各模型参数的计算方法；按测试需要所设计的这些测试图、卡可用ＶＡＸ机和通用微机生成；它们可直接用于ＨＤＴＶ计算机模拟系统，设置接口，可用于测试ＨＤＴＶ系统或设备
In this paper, the principle and method of mathematical model for testing HDTV image quality in Cartesian or polar coordinate system are studied. The methods for calculating the parameters of each model are quantitatively analyzed. The test charts Available with VAX machines and general purpose microcomputers; these can be used directly in HDTV computer simulation systems to set interfaces that can be used to test HDTV systems or devices
