使用MATLAB对特定信号进行频谱分析，画出幅度和相位谱的图像，并包含卷积运算和验证程序(The use of MATLAB to carry out a specific signal spectral analysis, to draw the magnitude and phase spectrum of images, and includes the convolution operation and the verification process)

Designs a frequency-domain and time-domain FIR equalizer for a single-input single-output (SISO) channel. Frequency-domain equalization uses a Chebychev criteria and is specified in terms of frequency response functions. It is a convex problem (which can be formulated as an SOCP): ( where H is the frequency response function and our variable is the filter impulse response h. Function G is the unequalized frequency response and G_des is the desired freq response. Time-domain equalization immediately designs the impulse response function by specifying the problem in time (it s an LP): minimize max_{t neq D} |g_tilde(t)| s.t. g_tilde(D) = 1 )
