Time	Narration
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.

02:27	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.
