用VC实现了一个波形发生器。可以发生方波、三角波、正弦波、矩形波等。幅度和频率可调-with VC of a waveform generator. It can happen square, triangle wave, sine wave, square wave, etc.. Adjustable amplitude and frequency

双音频信号处理，模拟电话的各个按键的波形发生情况-Dual audio signal processing, waveform of each key of the occurrence of an analog telephone

结合DSP可进行多波形发生，如正弦波，方波，锯齿波，三角波，并且可以进行各种波形之间的转换。-Combined with the DSP can occur for many waveform, such as sine wave, square wave, sawtooth wave, triangle wave, and can undertake various waveform conversion between.
