在数独高手的规则是要将9个数字填入一个9个小九宫格组成的9×9格子里。使得每一行，每一列和每个小九宫格里都有1－9的数字，并且每个数字在它所在的行、列以及每个小九宫格里面都只出现唯一一次。(Sudoku expert in the rules is to fill a 9 digit composed of nine small squares 9 × 9 grid yard. So that each row, each column and each have 1-9 small squares in the figures, and each figure in its row, column, and each small squares appear only inside the only time.)

AM&&DSB
用matlab产生一个频率为1Hz的余弦信源 ，设载波频率20Hz， ,试画出：
? AM及DSB调制信号的时域波形；
? 采用相干解调后的AM及DSB信号波形；
? AM及DSB已调信号的功率谱；
? 调整载波频率及m0，观察分的AM的过调与DSB反相点现象。(A cosine source with a frequency of 1Hz is generated by MATLAB, and the carrier frequency 20Hz is set.
The time domain waveform of AM and DSB modulation signals;
Adopt coherent demodulation of AM and DSB signal waveforms,
The power spectrum of AM and DSB modulated signals,
Adjust the carrier frequency and M0, observe the AM overshoot and DSB inverting point phenomenon.)
