程序实现fSK的发射机和接收机的解调过程，包括性能分析。绘制有关的性能曲线，和波形和频谱图。还可实现BFSK，MFSK。FSK解调时候，有两种解调方法：1包络解调法，2相干解调法。-program fSK transmitters and receivers demodulation process, including performance analysis. Drawing on the performance curve, and the waveform and spectrum. B

C#画坐标曲线,可以更改坐标的特性和曲线的特性-C# Plot Curve

5 最小二乘法的曲线拟合-Least-squares curve fitting method

实时数据曲线功能，可以调整量程大小，时间轴的大小(Real-time data curve function, can adjust the range size, the size of the time axis)
