Kauj Ruam 2: Ntws

Ib nthwv dej yog kev cuam tshuam uas hloov pauv lub zog los ntawm qhov teeb meem lossis thaj chaw, nrog me lossis tsis muaj kev cuam tshuam kev hloov pauv ntawm huab hwm coj. Cov yoj suav nrog kev yoj lossis kev co ntawm lub cev nruab nrab lossis thaj chaw, ib puag ncig qhov chaw ruaj khov. Los ntawm kev xav ntawm kev ua lej, nthwv dej, ua haujlwm ntawm lub sijhawm thiab thaj chaw, yog chav kawm ntawm cov cim. (Wikipedia)

Kauj Ruam 3: GNU Octave

GNU Octave software yog lub platform nyiam rau sawv cev thiab siv cov txheej txheem nthwv dej hauv lub khoos phis tawj. Octave nta cov lus qib lus qib siab feem ntau yog npaj rau kev suav ua lej. Octave muaj txiaj ntsig zoo rau kev ua ntau yam kev sim ua lej siv hom lus uas feem ntau sib xws nrog MATLAB. Raws li ib feem ntawm GNU Project, Octave yog software pub dawb raws li GNU General Public License. Octave yog ib qho kev xaiv pub dawb loj rau MATLAB, lwm tus yog Scilab thiab FreeMat.

Ua raws qhov txuas saum toj no txhawm rau rub tawm thiab teeb tsa Octave rau ib qho OS.

Qhia: Pib Pib nrog Octave

3. Chaw thau khoom, Txuag, thiab Siv Cov Ntaub Ntawv
4. Plotting Cov Ntaub Ntawv
5. Cov Lus Qhia Tswj
6. Kev ua haujlwm

Thaum nyob sab nraud ntawm peb qhov no ntawm cov nthwv dej yooj yim thiab ua suab, koj tuaj yeem pom qee lub siab tshuab cov khoom siv los ua haujlwm hauv Octave los ntawm kev tshawb fawb MATLAB xws li "DSP IN MATLAB" lossis "NEBR NETWORKS IN MATLAB". Nws yog lub zog muaj zog heev. Luav qhov mus tob heev.

Kauj Ruam 4: Lub Teeb Suab Sib Txuas

Lub suab cim tau tsim hauv lub khoos phis tawj tuaj yeem txuas ua ke nrog cov khoom siv sab nraud siv tus hais lus tso tawm ntawm daim npav suab. Ib yam li ntawd, lub microphone tso rau ntawm daim npav suab tuaj yeem siv tau yooj yim ob peb lub suab sab nraud tso rau hauv lub khoos phis tawj.

Siv daim npav USB suab yog lub tswv yim zoo rau cov ntawv thov los tiv thaiv kev ua kom lub suab tsis zoo ntawm koj lub khoos phis tawj motherboard yuav tsum muaj qee yam tsis raug. Ob peb ntawm 3.5mm suab thaj txuas cable thiab 3.5mm qhov kev tawm tsam yog qhov muaj txiaj ntsig zoo rau cuam tshuam kev sib txuas, hais lus, thiab tawm nrog cov chaw nres nkoj ntawm USB daim npav suab.

Ntxiv rau siv nrog GNU Octave, muaj qee qhov dej num txias txias nyob ib puag ncig rau Sound Card Oscilloscopes uas yuav tso cai rau koj "phiaj xwm" cov cim ntawm qhov tsawg zaus kom txaus los ua piv txwv los ntawm lub tshuab computer microcomputer.

Kauj Ruam 5: Lub Teeb Suab Hauv GNU Octave

Octave muaj qee qhov muaj txiaj ntsig zoo ua lub suab ua haujlwm.
