matlab软件编程实现虚拟的函数信号发生器-Function Generator

利用matlab编写的基于计算机声卡的虚拟仪器，含信号发生器、示波器和频率计，并利用matlab中guide可视化编程实现了界面操作。-Matlab prepared using computer sound card based virtual instrument, with the signal generator, oscilloscope and frequency meter, and use visual guide matlab programming in the interf

本文介绍了一个基于matlab和声卡的虚拟信号发生器的代码实现-This paper introduces a sound card based on matlab and virtual signal generator code realization

数字电子琴的功能是基于数字信号发生器的，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1234567共7个琴键，鼠标按下时即发声，松开时发声停止。-The function is based on the digital keyboard that is audible digital signal generator, digital signal generator generates by calling a series of specified
