说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

实现常用线路码型AMI（RZ）码的波形和功率谱密度的仿真。(achieve common line code-AMI (RZ) code and the waveform of the power spectral density of simulation.)

This Matlab code is written by me and its purpose is for car plate detection by using labeling and morphological operation. Its very fast and simple. for working on specific database it needs to change structural elements of morphological operation and also the area of white pixels in labeling part. for any information you can contact with me through my email.
