| 00:01 | Paralok, ngi pdiangsngewbha ia phi sha ka Spoken Tutorial halor ka Discrete Time System. |
| 00:07 | Ha kane ka jinghikai, ngin sa nang ban: |
| 00:09 | Convert hapdeng state space bad transfer function descriptions. |
| 00:14 | Define ia ka discrete time system bad plot ia ka step response jong ka. |
| 00:20 | Discretize ia ka continuous time system. |
| 00:23 | Nga pyndonkam da ka Ubuntu 12.04 operating system bad ka Scilab 5.3.3 na ka bynta ka jingbatai. |
| 00:31 | Ban pyrshang ia kane ka jinghikai, phi dei ban don ia ki jingtip ba donkam jong ka Scilab. |
| 00:36 | Lada phim don, sngewbha peit ia ki Scilab tutorials, ba don ha ka spoken-tutorial.org. |
| 00:44 | state space model: |
| 00:46 | x dot is equal to A x plus B u |
| 00:49 | y is equal to c x plus D u |
| 00:52 | La batai da ka sys three is equal to syslin into bracket into quotes c comma A comma B comma C comma D close bracket. |
| 01:05 | Na ka bynta ki matrices A,B,C, bad D ba la specify hashwa jong ki size ba iadei. |
| 01:11 | Plie ia ka Scilab ha ka computer jong phi. |
| 01:15 | Type: sys three is equal to syslin into bracket into quotes c comma four comma three comma six comma nine close bracket bad nion Enter. |
| 01:32 | Nion Enter ban bteng ia ka jingpyni. |
| 01:35 | Kane kadei ka nuksa na ka bynta single state, single input single output. |
| 01:40 | Ka output kan don ia ki A, B, C bad D bad initial state x zero |
| 01:49 | Type clc ban clear ia ka console. |
| 01:52 | Define, kum ka nuksa, matrices A, B, C, D ha Scilab console kumba phi iohi. |
| 02:00 | A is equal to open square bracket two space three semicolon four space five close square bracket, |
| 02:09 | Nion Enter. |
| 02:11 | B is equal to open square bracket one semicolon two close square bracket, |

| 02:27 | Bad nion Enter. |
| 02:30 | D is equal to two, |
| 02:33 | Nion Enter. |
| 02:35 | To ngin bujli ia kine ki matrices ha ka command ba hashwa. |
| 02:39 | sys four is equal to syslin into brackets into quotes c comma A comma B comma C comma D close bracket bad nion Enter |
| 02:57 | Phin ioh ia kane ka output harum. |
| 03:00 | Nion Enter ban bteng ia ka jingpyni. |
| 03:03 | Ka output kan don ia ki matrices A, B, C, D bad initial state x zero, kumba phi iohi. |
| 03:11 | Check lada ki poles jong ka sys4 kidei kijuh kum ka eigenvalues jong u 'A'. |
| 03:17 | Na ka bynta kane, phi lah ban pyndonkam p l z r function bad ka spec function. |
| 03:23 | Ka s s two t f command lah ban pyndonkam ban ioh ia ka transfer function jong ka state-space system sys S S. |
| 03:33 | Type ha ka Scilab Console jong phi "clc" ban clear ia ka. |
| 03:37 | Bad nangta type: sys capital 'T' capital 'F' is equal to s s two t f into bracket sys four close bracket bad |
| 03:50 | Nion Enter. |
| 03:52 | Phi iohi ia ka output. |
| 03:54 | Kadei ha ka rukom sys TF equal to ss two tf into bracket sys of SS. |
| 04:01 | Pyndonkam ss two tf function na ka bynta ka sys three ba la define hashwa. |
| 04:07 | sys T F udei u variable ba thymmai ha kaba ka 'denom' command ka long applicable. |
| 04:12 | Kam long applicable ia ka sys four, kumba ka long ha ka state space form. |
| 04:18 | Solve ia kane ka exercise harum. |
| 04:20 | Wad ia ka state space realization jong ka second order transfer function ba la define harum. |
| 04:26 | Pyndonkam ia ka t f two s s command. |
| 04:30 | Na ka bynta ka system bathymmai ha ka state space form, shu ong state space form, check lada ka eigenvalues jong ka matrix A bad ki poles jong katransfer function G of s kidei kijuh. |
| 04:43 | Pyndonkam ia ki matrices A, B, C, D jong ka system sys S S ban ioh ia ka transfer function, |
| 04:53 | Check lada ka jubab kadei ne em kaba long original. |
| 04:56 | Ngi define mynta ia ka discrete time system. |
| 05:00 | Ka long kaba biang ban pyndonkam ’z’ na ka bynta u variable ha u numerator bad denominator polynomials. |
| 05:07 | Kynmaw ba u variable ‘z’ u don ia u shortcut. |
| 05:11 | Ha ka jaka jong z is equal to poly into bracket zero comma inside quotes z pyndonkam z is equal to percentage z. |
| 05:21 | Leit sha ka Scilab console. |
| 05:23 | Type "clc" ban clear. |
| 05:26 | Type: z is equal to percentage z |
| 05:29 | Bad nion Enter. |
| 05:31 | Ngi define mynta ia ka first order discrete time system. |
| 05:35 | Ha ka Scilab Console, type: |
| 05:39 | D T System is equal to syslin into bracket into quotes small d comma z divided by inside bracket z minus zero point five close the bracket close outer bracket. |
| 05:59 | Nion Enter. |
| 06:02 | Ngi pyndonkam ia ka syslin function na ka bynta kane. |
| 06:05 | Ha kane ka kynti, ngi specify ia ka domain ban long discrete time ha ka jaka continuous time. |
| 06:13 | Na ka bynta ban check ia ka step response, ngi hap ban define ia ka input explicitly kum ones. |
| 06:19 | Kum ka nuksa: na ka bynta 50 points, |
| 06:22 | Type ha ka Scilab Console: |
| 06:25 | u is equal to ones into bracket one comma fifty close the bracket put a semicolon |
| 06:36 | Bad nion Enter. |
| 06:38 | Ha ka jaka jong csim, ngi hap ban pyndonkam ia ka flts function ban simulate ia kane ka system. |
| 06:45 | Type ha ka Scilab Console: |
| 06:48 | "clc" ban clear ia ka console. |
| 06:51 | y is equal to f l t s into bracket u comma D T System close bracket put a semi colon |
| 07:02 | Bad nion Enter. |
| 07:05 | Mynta, type: plot of y bad nion Enter. |
| 07:11 | Ka output kan sa shah plot. |
| 07:14 | Khang noh ia ka graphic window. |
| 07:17 | Ka long kaba iarap ban discretize ia ka continuous time system ba la ai. |
| 07:21 | Kane lah ban leh da kaba pyndonkam ia ka dscr function. |
| 07:25 | To ngin define ia ka continuous system s is equal to percent s bad |
| 07:32 | sys G is equal to syslin into bracket into quotes c comma two divided by into bracket s square plus two multiplied by s plus nine close bracket close outer bracket bad nion Enter. |
| 07:56 | To ngin discretize ia ka system sys G da ka sampling period jong zero point one. |
| 08:04 | Ha ka Console, type "clc" ban clear bad nangta type: |

| 08:25 | Nion Enter ban bteng ia ka jingpyni. |
| 08:28 | Kumba phi iohi, ka system la discretized kum A, B, C, D matrices bad inital state x zero. |
| 08:38 | Phi iohi ba ngi ioh ia ka discretized system ha ka state space representation. |
| 08:44 | Ngi lah ban pynkylla ia kane sha ka transfer function representation ha ka discrete time da kaba pyndonkam s s two t f function. |
| 08:54 | Na ka bynta kane, leit sha ka Scilab Console Window. |
| 08:58 | Type "clc" ban clear ia ka. |
| 09:01 | Mynta, type: sys six is equal to s s two t f into bracket sys five comma zero point one close the brackets bad nion Enter. |
| 09:18 | Ka output ka ai ia ka transfer function. |
| 09:22 | Ha kane ka jinghikai, ngi la pule ban : |
| 09:24 | Pynkylla hapdeng ki state space bad transfer function descriptions. |
| 09:28 | Define ia ka discrete time system bad plot ia ka step response jong ka. |
| 09:33 | Discretize ia ka continuous time system. |
| 09:36 | Peit ia ka video ba don ha ka link harum: |
| 09:39 | Ka kyllum lang ia ka Spoken Tutorial project. |
| 09:43 | Lada phim don ia ka bandwidth babiang, phi lah ban shu download bad peit ia ka. |
| 09:47 | Ka kynhun jongka Spoken tutorial project: |
| 09:49 | Ka pynlong ia ki workshops da kaba pyndonkam ia ki spoken tutorials. |
| 09:52 | Ka ai certificates sha kito ba pass ha ka outline test. |
| 09:56 | Na ka bynta kham bun ki jingtip, sngewbha thoh sha ka :contact@spoken-tutorial.org |
| 10:04 | Spoken Tutorial project kadei shibynta jong ka Talk to a Teacher project. |
| 10:08 | La kyrshan ia ka da ka National Mission on Eduction lyngba ka ICT, MHRD, Sorkar India. |
| 10:15 | Kham bun ki jingtip halor kane ka mission kidon ha ka : spoken-tutorial.org/NMEICT-Intro. |
| 10:27 | Nga i Meboreen na Shillong, nga pynkut ia kane. |
