VB写的教学用的信号频率生成器的源代码，有的称为信号调制模拟器，用来模拟2ASK、2FSK信号的调制过程，可供娱乐或教学；全部用的VB的算法，对学习算法也有帮助 。-The frequency of the signal generator source code written in VB teaching, some called signal modulated simulator, used to simulate 2ASK, 2FSK signal modulation proc

用VB写的教学用的信号频率生成器，比较经典-Using VB to write teaching signal frequency generator, more classic

simulink仿真模型，通过一个频率可变的三角波生成器，调制出频率可变的信号。(The Simulink simulation model modulates a variable frequency signal through a variable frequency triangular wave generator.)
