已知采样频率80000，通带衰减0.5阻带衰减45 通带截止频率4000，阻带截止频率20000，用双线性变换法设计数字低通滤波器 (Known sampling frequency 80000, attenuation in the passband stop-band attenuation 45 0.5 Passband cutoff frequency of 4000, 20,000 stopband cutoff frequency, using bilinear transform design digital low-pass filter)

说明：  用matlab编写的关于车牌识别的字符分割的程序。(Matlab prepared by using the character segmentation of license plate recognition program.)

可以很好的实现车牌的定位（粗细定位）两步实现。(Can realize a good positioning plate (thickness positioning) two-step to achieve.)

直接序列扩频就是直接用具有高码率的扩频码序列在发端去扩展信号的频谱。而在收端，用相同的扩频码序列去进行解扩还原成原始的信息。(Direct Sequence Spread Spectrum is the direct use of the spreading code sequence with a high rate in the originator to expand the spectrum of the signal. Receiving end, using the same spreading code sequence to despread the broadening of the spread spectrum signal to restore the original information.)
