2.5.3
利用firpmord和firpm函数设计双带通滤波器,其指标为,第一带通指标:f =4kHz,f =5 kHz ,f =3.6 kHz ,f =5.4 kHz
第二带通指标:f =6kHz,f =7 kHz ,f =5.6 kHz ,f =7.4 kHz
通带衰耗A <3dB,阻带衰耗A >40dB,抽样频率f =20kHz。(Double belt pass filter using firpmord and firpm function design, for its indicators, through the first area index: f = 4 kHz, f = 5 kHz, f = 3.6 kHz, f = 5.4 kHz
The second bandpass indicators: f = 6 kHz, f = 7 kHz, f = 5.6 kHz, f = 7.4 kHz
Pass band attenuation A < 3 db, stop-band attenuation A > 40 db, f = 20 KHZ sampling frequency.)

Shape-Recognition
這是一個可以自動尋找图像中的長方形, 正方形, 圓形, 菱形的程式(1- Read the RGB (colored) image in from user.
2- Convert image from (RGB) colored to gray image.
3- Threshold the image (convert gray image to binary image).
4- Invert the binary image (in order to speed up the time of processing).
5- Find the boundaries concentrate.
6- Determine shapes properties (ratio of dimensions, roundness).
7- Classify shapes according to its properties. )
