【Abstract】 In this paper, the principle and the method for developing the mathematical models of various test patterns and test cards in rectangular coordinate system and polar coordinate system are presented.And then the method for calculating the model parameters is quantitatively analyzed. The test patterns and cards are designed according to the test need and are also generated on VAX or microcomputer. They can directly used in the simulation system of HDTV. Forthermore, through necessary interface circuits, they can be used to test real HDTV systems or equipment.更多还原
