| 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. 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- 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. 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. |
