一阶sigma-delta ADC 算法仿真程序及量化台阶可视化(oneorder sigma-delta ADC simulation code and quatity ladder)

This routine draws a square with center defined as X_CENTER,Y_CENTER and lattice LATTICE.

将一个512×512的lena.bmp图像进行DCT变换，对得到的DCT系数按8×8块进行分层（分三层），重组填充得到新的系数矩阵，结果发现原图像的能量集中在了新图像的左上角低频部分。(The lena.bmp an image of 512 × 512 is subjected to DCT transform, the DCT coefficients obtained by layering 8 × 8 block (of three), to obtain a new recombinant filling coefficient matrix, the energy of the original image is found concentrated in upper left corner of the low-frequency part of the new image.)
