数字电子琴的功能 电子琴的每个音阶均对应一个特定频率的信号，通过调用数字信号发生器产生一系列指定的频率的声音，从而达到虚拟的电子琴的功能，界面中包含A、B、…、O共 15 个琴键，鼠标按下时即发声，松开时发声停止。 同时能够产生正弦波、方波、三角波等常见的波形的数字信号，并且提供了图形界面用于选择波形、频率、幅值与相位。能够根据用户指定的波形和参数产生相应的数字信号，然后将数字信号写入声卡的缓冲区，最后由声卡播放出相应的声音。 -Digital electronic keyboar

Matlab的窗函数_矩形窗_三角窗_汉明窗_汉宁窗_布莱克曼窗-The window of the Matlab function, rectangle, triangle window, hamming window and hanning window, blackman window

I am trying to representate a SPWM comparing a 30kHz triangle wave with a 60Hz sine wave using the MatLAB. However, I do not know how to compare two functions in him. Recently I generated this graph containg the sine and the triangle wave functions..
