The concerted control strategy of rectifier and inverter is analyzed to keep high modulationdegree of SPWM, which achieves quick response and high resolution of excitation voltage regulation.
According to optical transfer function, degree of modulation and apperceive degree of space frequency vision vs object image, TIFF grayscale scenograph is made.
根据光学传递函数、调制度和空间频率视觉及对物象的感知程度，制作TIFF格式透视灰度图。
