小学期的源程序
1.试编MATLAB程序。信号 sinc(10*t),-2<=t<=2
m(t)=
0,其它
用100hz的载波来产DSB信号并解调。完成下列工作:
画出已调信号;
求已调信号的频谱,并用图像表示。
画出解调信号;
求解调信号的频谱,并用图像表示。
2.信号
sinc2(100t),|t|≤t0
m(t)=
0, 其它
采用频率调制调制为1000HZ的载波。频偏常数为kf=50,t0=0.2。
注:(求和代替积分)
3.信号
2, t0/3>t>0
m(t)= -6, t0/3<=t<2*t0/3
0, 其它
t0=0.15,使用AM调制和包络检波解调.(Primary phase of source 1. Test procedures for MATLAB. Signal sinc (10* t),-2 < = t < = 2 m (t) = 0, the other with the 100hz signal carrier to the middle class and DSB demodulation. To complete the following tasks: Draw has been transferred signal for the spectrum signals have been adjusted, and image representation. Draw demodulation signal solving transfer spectrum signal, and image representation. 2. Signal sinc2 (100t), | t | ≤ t0 m (t) = 0, the other the use of frequency modulation of the carrier modulation for 1000HZ. Offset constant kf = 50, t0 = 0.2. Note: (sum in lieu of points) 3. Signal 2, t0/3> t> 0 m (t) =-6, t0/3 < = t < 2* t0/3 0, other t0 = 0.15, the use of AM modulation and demodulation envelope detector.)

to-determine-a-leap-year
3、 题目:输入1842——2006年之间的十进制数。
要求:
(1) 要求必须有提示信息,并独占一行。
(2) 判断是否是闰年,如果是输出“yes”,否则输出“no”。 (提示:先除100,如果除尽了再用400除如果除不尽是闰年。(如果刚才的100没有除尽则用4除,除尽则为闰年。)
(3) 以二进制输出xxxx年8月29日距离1842年8月29日的月数。
(4) 以十进制输出xxxx年8月29日距离1842年8月29日的天数。
(3, the title: Enter 1842--2006 decimal number between the years. Requirements: (1) requires the existence of a message, and its own line. (2) to determine whether it is a leap year, if the output " yes" , otherwise output " no" . (Hint: first addition to the 100, except if divisible by the then 400 is a leap year if the indivisible (If you just use the 100 is not divisible by 4 except, divisible was a leap year.) (3) in the binary output xxxx August 29 from August 29, 1842 the number of months. (4) decimal output xxxx years from August 29, August 29, 1842 the number of days.)
