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 Haei
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" is the default model used for transistor "mod1", in the circuit.

“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 0.2 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.
