Y Parameter na Nani?

Y parameters (ko da ake kiran admittance parameters ko short-circuit parameters) suna yin hanyoyin da ake amfani da su a sayarautar karkashin kula don bayyana tattalin kula da ke faruwa a cikin shugaban kula mai tsari. Ana amfani da wasu Y-parameters a matsayin Y-matrixes (admittance matrixes) don taka takammiya da kuliya daga cikin shugaban kula.

Y-parameters suna kira “short-circuit impedance parameters”, saboda ana taka su ta hanyar yanayin hankali. Wannan yana nufin cewa Ix=∞, idan x=1, 2 yana nuna kuliyan da ke faru a kan mazaunin shugaban kula biyu.

Y parameters suna amfani da su a tsohon Z parameters, h parameters, da ABCD parameters don modeli da bayyana lines of transmission.

Ana Taka Y Parameters a Shugaban Kula Biyu

Misalai na a nan ya kawo cewa za a taka Y parameters daga shugaban kula biyu. Zaka iya amfani da kalmomin admittance parameters, da za su iya amfani da su ta hanyar misalai.

Idan an yi bayyana Z parameters (ko da ake kiran impedance parameters), zan iya rubuta takammiya a kan kuliya ta hanyar wannan kalmomi.

Duk da haka, zan iya rubuta kuliya a kan takammiya ta hanyar admittance parameters daga shugaban kula biyu. Don haka za a rubuta nuna-nunan kuliya da takammiya,

Wannan zan iya rubuta a matsayin matris,

A nan, Y11, Y12, Y21, da Y22 suna kira admittance parameters (ko Y parameters).
Zan iya samun ukuwar parametoru daga wata shugaban kula biyu ta hanyar yanayin hankali a kan mazaunin output da input port.
Bisa ga, zan iya sanya current source ta I1 a kan input port ta hanyar yanayin hankali a kan output port, kamar yadda aka nuna a nan.

A nan, takammiya a kan output port zai kasance zero saboda mazaunin port suna zama yanayin hankali.

Na gaba, al'ada ta input current I1 zuwa input voltage V1 inda output voltage V2 = 0, ita ce

Wannan yana kiran short circuit input admittance.
Al'ada ta output current I2 zuwa input voltage V1 inda output voltage V2 = 0, ita ce

Wannan yana kiran short circuit transfer admittance daga input port zuwa output port.
Na gaba, zan iya yanayin hankali input port ta shugaban kula da kuma sanya current I2 a kan output port, kamar yadda aka nuna a nan.

A nan,

Wannan yana kiran short circuit output admittance.
