In this coursework, a mthematical model is derived for a dynamic system consisting of a LRC circuit (inductance, resistance and capacitance respectively ) and will be simulated using the MATLAB.

Matlab中simulink仿真-答案(Matlab simulink simulation- the answer)

利用matlab编程实现LPC谱与语音频谱的比较。( LPC spectrum using matlab programming comparison with the speech spectrum)

这是频域副本相关的代码，给予信号同样长度的副本，使得信号在相关后可以恢复，先是通过滤波器，然后找出信号点。(This is related to the frequency domain replica code, a copy of the same length given signal so that the signal can be restored after correlation, first through a filter, and then identify the signal points.)
