应用频域平滑方法绘制的循环周期谱图，同时给出了f轴和alpha轴的截面图。(Application of frequency domain smoothing method to draw the cycle of spectrum, and gives the f-axis and the alpha-axis sections.)

本文介绍了基于MATLAB软件在《信号与系统》课程教学中的仿真实验,通过抽样信号的表征、周期方波信号的傅立叶级数分解与合成、余弦信号的相加与相乘、RLC带通滤波器的频率特性等仿真实验,说明了将MATLAB应用于教学实践中的重要作用和意义。(This article describes the MATLAB-based software in the " Signals and Systems" course teaching simulation, by sampling the signal characterization, cycle square wave signal of the Fourier series decomposition and synthesis, and the sum of cosine signal is multiplied, RLC bandpass filter the frequency characteristics simulation, MATLAB used to illustrate the important role of teaching practice and significance.)

This program is to plot 3-D radiation pattern of 2-element array antenna.

matlab经典课堂讲义 是初学者的好资料。(Classic class handouts for matlab ，its good Information for the beginner )

1、观察采样引起的混叠。 2、判别离散时间系统的时不变性。 3、利用卷积计算信号通过FIR滤波器的输出，并观察输出信号的input-on暂态、input-off暂态和稳态阶段。 (One to observe the sampling due to aliasing. 2, determine the time invariant discrete-time systems. 3, the use of convolution calculation of the signal through the FIR filter output, and observe the output signal of the input-on transient, input-off transient and steady-state phase.)

说明：  cholesky分解，求解一般的线性方程组很方便。(Cholesky decomposition, for solving general linear equations easily.)

说明：  主要是matlab7.0在数字信号处理中的应用，仅供初学者看，本人是菜鸟级人物。(Mainly matlab7.0 in digital signal processing applications, only a beginner, I was the rookie-level characters.)
