adhika impedence

electronicslo, adhika impedence antey sarkyuutlooni oka point (node) aaa samayamlo vartimpajesina voltage yokka prati unitku saapekshamgaa takkuva mottamlo karentnu anumatistundi. adhika impedence circuitlu takkuva current mariyu adhika voltage kaligi untaayi, ayithe takkuva impedence circuitlu dheeniki viruddhamgaa untaayi (takkuva voltage mariyu adhika current kaligi untaayi). adhika impedence" yokka sankhya nirvachanalu anuvartanaanni batti maarutuu untaayi.
volt meterlu ledhaa asyllascopes vanti koliche parikaraalapai adhika impedence inputlaku praadhaanyata istaaru. audeo vyavasthalalo, christal microphonelu ledhaa adhika antargata impedence unna itara parikaraalatoe upayoginchadaaniki adhika-impedence input avasaram kaavacchu.
analog electronics.
analog circuitlalo adhika impedence node anedi "pariganinchabadutunna frequency paridhiloo" yea itara nodlaku takkuva impedence margalu laenidi. takkuva mariyu ekkuva anae padaalu kontavaraku sandarbhampai aadharapadi untaayi kabatti, konni adhika impedence nodlanu oka sandarbhamlo takkuva impedensga mariyu maroka sandarbhamlo adhika impedensga varninchadam suutrapraayamgaa saadhyamavutundi; kabatti node (bahusha signal soars ledhaa amplifier input) voltagelaku "saapekshamgaa takkuva currents" kaligi untundi.
adhika impedence nodes adhika ushna sabdam voltagelanu kaligi untaayi mariyu capacitive mariyu inductive sabdam pickup kuu ekkuvagaa untaayi. pareekshinchetappudu, asyllascope ledhaa multimeter yokka impedence node meeda signal ledhaa voltagenu bhaareega prabhaavitam cheyagaladu kabatti vaatini pariseelinchadam tarachugaa kashtam. adhika impedence signal avutputlu konni transducerla (christal pikaplu vantivi) lakshanam; vatiki anusandhaaninchabadina amplifier nundi chaalaa ekkuva impedence load avasaram. prastuta buffer circuitlu ledhaa step-down transformerlu adhika-impedence input muulaanni takkuva impedence amplifiertho saripolchagalavu ayinappatikee, vacuum tube amplifierlu mariyu feeled effect transisterlu bipolar junction transister-aadhaarita amplifierla kante adhika-impedence inputlanu marinta sulabhamgaa sarafara chestaayi.
digital electronics.
digital circuitlalo, adhika impedence (hye-jedd, trai-stated ledhaa floating anie kooda pilustaaru) avtput avtput circuit dwara yea nirvachinchina logic sthaayiki nadapabadadu. signal taarkikamgaa adhika ledhaa takkuva sthaayiki nadapabadadu; eee moodava paristhiti "tri-perkonna" vivaranaku daariteestundi. atuvanti signalnu open circuit (ledhaa "floating" wire) gaa chudavachu, endukante daanini takkuva impedence circuitku anusandhaaninchadam aaa circuitnu prabhaavitam cheyadu; badulugaa adhi churukuga nadiche avtput vale adhe voltage kii laagabadutundi. aneka iclapy kanipinche samyukta input/avtput pinlu vaastavaaniki tri-sthithi saamarthyam kaligina avutputlu, ivi antargatamgaa inputlaku anusandhaaninchabadi untaayi (phalitamgaa moodu-sthithi tarkam ledhaa naalugu-viluva gala tarkam). aneka itara upayogaalato paatu computerlalo bassu-vyavasthalaku idhi aadharam.
circuitlo icchina node yokka adhika-pratighatana sthithini voltage kolata dwara matrame dhruvikarinchalemu. vairnu adhika (ledhaa takkuva) voltage sthaayiki laagadaaniki pull-up resister (ledhaa pull-down resister) nuu madhyastha-nirodhakam muulamgaa upayoginchavacchu. node adhika-pratighatana sthithilo lekapothe, nirodhakam nundi vachhe adanapu current daani voltage sthaayini gananeeyamgaa prabhaavitam cheyadu.
