预先设定载频、采样率、码速率、信息代码个数和信噪比等参数，进行FSK信号的调制解调。-Pre-set carrier frequency, sampling rate, bit rate, information, code number and signal to noise ratio and other parameters for FSK signal modulation and demodulation.

试设计一个切比雪夫I型高通数字滤波器，采样率为8000Hz,fp=1000Hz,fs=700Hz,Rp=3dB,Rs=20dB。-Try to design a type I Chebyshev high-pass digital filter sampling rate of 8000Hz, fp = 1000Hz, fs = 700Hz, Rp = 3dB, Rs = 20dB.
