用MATLAB实现数值分析的不同计算方法的实现过程，是研究生一年级需要的(Numerical Analysis Using MATLAB to achieve the realization of a different method of calculation process is required first-year graduate students)

2FSK是利用数字基带信号控制在波的频率来传送信息。经过调制后的2FSK数字信号通过两个频率不同的带通滤波器f1、f2滤出不需要的信号，然后再将这两种经过滤波的信号分别通过包络检波器检波，最后将两种信号同时输入到抽样判决器同时外加抽样脉冲，最后解调出来的信号就是调制前的输入信号。(gudi hduidf hdag sdd w)
