Time	Narration
00:01	Ngi pdiang sngewbha iaphi sha ka spoken Tutorial halor ka “DC sweep analysis in Ngspice”.
00:07	Ha kane ka jinghikai ngin pule shaphang:
00:09	Kumno ban leh ia ka DC sweep analysis bad Nested DC sweep analysis.
00:14	Khyndiat ki jingtip shaphang ka electronic circuits kalong kaba donkam na ka bynta kane ka jinghikai.
00:19	Khyndiat ki jingtip halor ka Ubuntu Linux bad shell commands ruh kalong kaba donkam.
00:25	Ka Ubuntu 12.04 kadei ka operating system kaba ngi pyndonkam bad ka ngspice bershon 23 ba la dep install.
00:33	Ngin pyndonkam da ka circuit ba la pyni ha ka nuksa .
00:36	Ka circuit kadon ia ki lai tylli ki nodes ba kham shon - “1”, “2” bad “3”.
00:40	Ryngkat lang , u node uba 4 uba ngi khot reference lane datum node dei ban buh kum u node ba “0”
00:47	Kane kalong ba donkam bha na ka bynta kino kino ki circuit.
00:51	To ngin plie ia ka ngspice netlist file “example.cir” kaba iadei bad ka circuit schematic kumba la pyni ha shwa, ha ka text editor.
01:00	Nga la plie lypa ia kane ka file ha ka jaka pynbeit dak gedit.
01:04	Kynmaw ba ka netlist file lah save ha ka “.cir” extension.
01:10	Ngi lah ban iohi ba baroh ki bynta kum ka voltage source, resistors bad ki jingtip halor ki nodes kiba pynïasnoh lang ia ki baroh.
01:18	‘dc’ command kaba la kynthup lang ha ka netlist file la pyndonkam lang ban pyntreikam ia ka dc sweep analysis.
01:25	Ka rukom ban pyndonkam ia ka ‘dc’ command la pyni hangne.
01:29	dot DC SRCNAM VSTART VSTOP VINCR
01:35	Ha kaba
01:37	SRCNAM kadei ka kyrteng jong ki bynta ba mih jong ka voltage bad current ha la ki jong.
01:42	VSTART, VSTOP bad VINCR kidei ki dak kiba pyni ia ki jingsdang, jingkut bad ka jingkiew na ka bynta ka source.
01:51	Kumba phi iohi, ngi lah pynpher ia ka voltage source V1 na ka bynta kawei ka value kaba 24 VOLTS ha ka rukom khein ba kiew shi kyrdan.
02:02	Mynta, ngin simulate ia kane ka circuit bad ngin wad ia ka jigkdew voltage ha man la ki nodes.
02:08	To ngin plie ia ka ngspice lyngba ka terminal.
02:11	Ñion control, Alt, T ha kajuh kapor.
02:14	Kane kan plie ia ka Terminal window.
02:18	Mynta ngan leit sha ka pholdar kaba ia ka netlist file, ‘’example.cir” la save.
02:23	Nga leh ia kane kumne harum:
02:26	cd downloads ia ka lynti sha ka pholdar bad ñion Enter.
02:33	Mynta, to ngin pynkylla khyndiat ia ka ngspice file.
02:36	To ngin peit kumno ban leh ia kane.
02:39	Ha ka terminal.
02:40	Type: ngspice space example.cir bad sa ñion Enter.
02:51	Value jong u voltage v1 kadei 2.4 volts.
02:56	Value jong u voltage v2 kadei 9.746 volts.
03:01	Kiwei pat ki node voltage ruh la pyni.
03:05	Kaba bud pat ngin peit kumno ban leh ia ka nested dc sweep analysis.
03:10	Ka Generalized form naka bynta kane ka long kumba la pyni.
03:14	Dot DC SRCNAM VSTART VSTOP VINCR SRC2 START2 STOP2 INCR2
03:24	Ha kaba
03:26	SRCNAM Ka dei ka Primary sweep variable bad SRC2 ka dei ka Secondary sweep variable.
03:33	Secondary sweep variable ka pynlong ia ka loop kaba shabar.
03:36	Kata kadei, na ka bynta ka jingkiew jong ka secondary sweep variable, kaba nyngkong ka sweep variable ka rung lyngba ka range jong ki values.
03:45	Kan kham shai ryngkat ka nuksa jong ka circuit kaba ngin simulate.
03:50	Ngin pyndonkam da ka Bipolar junction transistor based circuit ha ka common base configuration.
03:56	Primary sweep variable kadei ka voltage Vin, kaba la iasohlang hapdeng ka emitter bad ka base terminals.
04:03	Secondary sweep variable kan long ka load resistor ‘Rload’.
04:08	Ngin sa thoh ia ka output voltage pyrshah ia ka input voltage, na ka bynta ki values jong ka load resistor.
04:14	Ka output voltage kadei ka voltage shiliang jong ka ‘Rload’ bad ka input voltage kadei ka ‘Vin’.
04:21	Kine harum ki dei ki netlist kiba don ka jingiadei bad ka common base transistor circuit.
04:26	“NPN” kadei ka default model kaba pyndonkam na ka bynta ka transistor “mod1”, ha ka circuit.
04:33	Kumba phi lah ban iohi, ka “Vin’ ka iapher na ka 0.2 volts sha ka 2 volts da ka jingkiew kaba 0.02 volts.
04:45	‘Rload’ ka iapher na ka 5 kilo-ohms sha ka 10 kilo-ohms da ka jingkiew kaba 2 kilo-ohms.
04:53	Na ka bynta ka values jong ka ‘Rload’, ka ‘Vin’ ka pynkhuid ia baroh ki range naduh ka 0.2 haduh 2.
04:59	Ka graph jong ka output-voltage pyrshah ia ka input-voltage la pyni man ka khep.
05:05	Plot v of 3 comma 4 ka pyni ia ka voltage drop hapdeng ki nodes 3 bad 4, kata kadei ka voltage shiliang jong ka ‘Rload’.
05:15	Mynta, ngin simulate ia kane ka circuit bad ngin peit ïaka ba mih.
05:19	Ha ka terminal, type:source space example nested.cir bad ñion Enter.
05:35	Kane kan run ia ka simulation.
05:37	source, command la pyndonkam ban simulate ia ka netlist napoh jong ka ngspice, simulator environment.
05:44	Kumba phi lah ban iohi, ka graph jong ka output-voltage pyrshah ia ka input-voltage la plot na ka bynta ki value kiba pher ba pher jong ka load resistor.
05:52	Ïehnoh ia ka ngspice simulator da kaba type “quit” bad sa ñion Enter.
05:59	Mynta ngi lah poi sha kaba kut jong kane ka jinghikai.
06:02	Ha kane ka jinghikai, ngi la pule shaphang:
06:04	Kumno ban leh-
06:05	*DC sweep analysis jong ka circuit ba la ai lypa.
06:08	*Nested DC sweep analysis jong ka circuit ba la ai lypa.
06:12	Peit ia ka video kaba don ha kane ka link harum.
06:14	Ka batai kyllum ia ka Spoken Tutorial project.
06:18	Lada phim don ia ka bandwidth kaba biang, phi lah ban shu download bad peit ia ka hadien.
06:22	Ka kynhun jong ka Spoken Tutorial project:
06:24	*Ka pynlong workshop da kaba pyndonkam da ka spoken tutorials.
06:27	*Ka ai ceritifcate sha kito kiba pass ha ka online test.
06:31	Na ka bynta ki jingtip ba kham bniah sngewbha thoh sha: “contact at spoken hyphen tutorial dot org”
06:37	Spoken Tutorial kadei shi bynta jong ka Talk to a Teacher projek.
06:41	La kyrshan ia ka da ka National Mission on Education lyngba ka ICT, MHRD, ka Sorkar India.
06:47	Ki jingtip khambun halor kane ka mission kadon ha ka:
06:51	spoken hyphen Tutorial dot org slash NMEICT hyphen Intro
06:58	Khublei ba phi la ïasnohlang.
06:59	Nga kyrmen ba kane ka jinghikai kalong jingmyntoi iaphi.
07:02	Ia kane la pynkylla sha ka ktien Khasi da i Hezekiah Lyngdoh na Meghalaya, Shillong.
