2 Pergi, 1 Datang Lagi…

Minggu ni menghadapi 3 proposal untuk assignment. Pagi tadi baru saja selesai menyiapkan 2 daripadanya. Jadi tinggal satu lagi yang masih berkayuh. Luahan rasa lega dapat dilepaskan. Namun kemudian…

“tingenit-ngenit ningenit-ningenit”      (ulang 2 kali)

Telefon bimbit menyanyi lagu menandakan satu mesej telah masuk. 01362602**… nombor yang asing, tak kenal. Bila dibuka, tertera di dalamnya :

“Kamil, dsp assignment dah kuar, aku buat ngan ko boleh? 1 group 2 org je..”

Lalu aku balas dengan ayat agak skema, “Siapekah kamu?”

“Aku la… Beng.. Ni no celcom baru aku..”.

Owh… rakan sekelas rupenye. Tapi yang timbul di hati, kepala, badan, usus bukan lagi kelegaan, sebaliknya kejutan. Bertambah semula bilangan kerja… Apa yang perlu dibuat untuk assignment DSP? Bacalah sendiri :

Digital Signal Processing

Problem 1

With all the provided specifications, answers the questions given to design a bandpass FIR filter. Useful MATLAB M-file :-

to verify your calculation : firl, boxcar and kaiserord, kaiser;

to plot the magnitude response : freqz, fft and plot.

Problem 2

Design a digital Butterworth lowpass filter operating at a sampling rate of 8 kHz with less than 3 dB of ripple up to 2500 Hz and a minimum stopband of 30 dBfrom 3000 Hz using bilinear transformation method. Useful MATLAB M-file :-

to verify your calculation : buttord and butter;

for filtering purpose : wavread, soundsc and filter;

to plot the magnitude response : fft and plot.


p/s : Lagi masalah bila terlepas makmal Selasa lalu. Beginilah kesannya, kelam-kabut jadual bila subjek tahun seterusnya perlu diambil tahun ini… adeii~!
