【正文】 aking a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the organisations listed underg an employment tribunal claimEmployment tribunals sort out disagreements between employers and employees.You may need to make a claim to an employment tribunal if:通過這次課設(shè)，使我對(duì)濾波器有了更深的認(rèn)識(shí)，特別是濾波器參數(shù)對(duì)濾波器性能的影響，因?yàn)橥◣Ы刂诡l率、阻帶截止頻率、通帶波紋系數(shù)、阻帶波紋系數(shù)都是要影響濾波器的階數(shù)，而濾波器的階數(shù)越大，其選頻特性就越好?？梢钥闯觯吞匚炙紴V波器的頻率特性曲線無論在通帶還是在阻帶內(nèi)，都是頻率的單調(diào)函數(shù)，切比雪夫Ⅰ型濾波器的幅頻特性在通帶內(nèi)是等波紋的，阻帶內(nèi)是單調(diào)的。sound(y,fs,bits)。[h,f]=freqz(num,den,256,fc)。)。)[N,Wc]=buttord(wp,ws,rp,rs)。fs=[3000,8000]。axes()。endx=filter(num,den,y)。ws=2*fs/fc。e:\39。axes()。[num,den]=cheby1(N,rp,Wc,39。if get(,39。)。 %求濾波器的頻率響應(yīng)。 %將x信號(hào)進(jìn)行快速傅里葉變換。 %估算切比雪夫Ⅰ型濾波器的階數(shù)N和截止頻率Wc。value39。rp=。這里，雖然GUI自動(dòng)生成了回調(diào)函數(shù)，但是回調(diào)函數(shù)是空的。 2） 掌握在 Windows 環(huán)境下語音信號(hào)采集的方法。其發(fā)展方向也是多方面的，包括數(shù)字匯聚、遠(yuǎn)程會(huì)議系統(tǒng)、融合網(wǎng)絡(luò)、數(shù)字圖書館、圖像與文本合一的信息檢索業(yè)務(wù)、多媒體通信、個(gè)人信息終端等。數(shù)字信號(hào)處理的應(yīng)用包括濾波與變換、通信、語音、語言、圖像、圖形、消費(fèi)電子、儀器、工業(yè)控制與自動(dòng)化、醫(yī)療、軍事等。2．課程設(shè)計(jì)基本要求 1） 學(xué)會(huì) MATLAB 的使用，掌握 MATLAB 的程序設(shè)計(jì)方法。 設(shè)置回調(diào)函數(shù)：。fs=2000。if get(,39。[N,Wc]=cheb1ord(wp,ws,rp,rs)。X=fft(x)。[h,f]=freqz(num,den,256,fc)。e:\39。ws=2*fs/fc。else [N,Wc]=cheb1ord(wp,ws,rp,rs)。plot(x)。3）“帶通”按鍵的回調(diào)函數(shù)function pushbutton3_Callback(hObject, eventdata, handles)[y,fs,bits]=wavread(39。wp=2*fp/fc。[num,den]=cheby1(N,rp,Wc)。[h,f]=freqz(num,den,256,fc)。fp=[1000,10000]。value39。stop39。plot(abs(X))。)。三、調(diào)試分析圖1 控件布局圖2 單擊“激活運(yùn)行”后界面圖3 巴特沃思高通濾波器圖4 切比雪夫高通濾波器圖5 巴特沃思低通濾波器圖6 切比雪夫低通濾波器 圖7 巴特沃思帶通濾波器 圖8 切比雪夫帶通濾波器 圖9 巴特沃思帶阻濾波器圖10 切比雪夫帶阻濾波器圖3—圖10為巴特沃思和切比雪夫Ⅰ型濾波器在不同頻率特性下產(chǎn)生的信號(hào)波形與頻譜，同時(shí)有原信號(hào)作對(duì)比。所以根據(jù)各個(gè)濾波器的選頻范圍及濾波后信號(hào)的音效，可大致判斷原信號(hào)的頻率多集中在1000Hz以下。此外還要特別感謝指導(dǎo)老師耐心的輔導(dǎo)，并幫助我糾正錯(cuò)誤，授予以魚，亦之以漁，使我不僅能夠按時(shí)完成課程設(shè)計(jì)，也從中對(duì)本課程有了更深的認(rèn)識(shí)與理解，同時(shí)也注意到自己在學(xué)習(xí)方法中的不足，并會(huì)在日后加以改正。against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal.Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept it.If you are worried about how the time limits apply to you, take advice from one of the organisations listed underTo find your nearest CAB, including those that give advice by , click onfor the racist behaviour of their fans during總覺得自己自己似乎應(yīng)該去做點(diǎn)什么，或者寫點(diǎn)什么。Originally, this world, can produce a chemical reaction to an event, in addition to resolutely, have to do, and time.　　原來，這個(gè)世界上，對(duì)某個(gè)事件能產(chǎn)生化學(xué)反應(yīng)的，除了非做不可的堅(jiān)決，還有，時(shí)間。 Those were broken into various shapes of stationery。t.
