FFT和Hilbert变换工具包，但是和MATLAB相比要慢些(FFT and Hilbert transform tool kits, and MATLAB slower than some)

说明：  在matlab中充分利用simulink的强大功能仿真通信系统中的调幅。(In matlab to make full use of the power of simulink simulation of communication systems in the AM.)

该文件是一个详细分析PID控制的文件。通过示波器，改变参数下，可以很形象的观察输出波形的变化，这样可以更加直观的学习PID控制，加深对它的理解(The file is a detailed analysis of PID control file. Through the oscilloscope, change the parameters, can be very image of the observed output waveform change, so that we can more intuitive learning PID control, deepen the understanding of it )
