我编写的声卡示波器 能够显示波二路波形，还可以产生所需的三角波，正弦波，方波等-I prepared to demonstrate sound card oscilloscope waveform wave two-sample, can have the triangular wave, sine wave, square, etc.

this program calculates the twiddle factors, generator sine wave with user setting sample rate, signal frequency. The user interface gives parameter setting of sample frequency, signal freqency and number of sample and so on.

ECG wave genrator a sample simulator program.Modifications according to requiremnts can be done.
