这是我们现代通信原理课程设计时所写的一个关于模拟信号的调频（FM）、双边带调幅（DSB）程序，里面还有详细的报告。(This is our modern communication principles course design of a written about analog signals (FM), the frequency modulation (DSB) with bilateral program, with detailed report.)

分析了计算四波混频效率的表到式在考虑非线性相位失配因子和不考虑非线性相位失配因子两种情况下，四波混频效率计算的差别(Analysing the expression of DFWM in the optical fiber under the consideration of nonlinear phase mismatch factor, then comparing the result to the expression which includes only linear phase mismatch factor.)

用最大距离法对K均值的初始聚类中心进行确定(max distance algorithm)

Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )
