Manatu taua o PCB fetaui lelei mamanu:

1, matagaluega laupapa fesoʻotaʻiga e matele lava atagia mai i le electromagnetic ogatasi, ma electromagnetic ogatasi mafai ona malamalama i ai o le matagaluega laupapa i le tele o eletise eletise siʻosiʻomaga mafai ona tausisia le mafai e faʻamaopoopo ma galue lelei, muamua o mea uma, o le muamua faʻataʻitaʻiga laupapa matagaluega electromagnetic ogatasi o uaea lautele, uaea lautele fuafuaina le inductance tuufaatasiga o lolomi uaea, Inductance tuufaatasiga fuafuaina le aafiaga faalavelaveina gafatia o le tumau taimi nei i luga o le matagaluega laupapa, o lea o se talafeagai filifiliga o uaea lautele mafai ona faaitiitia ai le electromagnetic faalavelave.
2, i le faʻaopopoga i le inductance, lolomi faʻapipiʻi mafai ona aʻafia luga o le matagaluega uaea laupapa e aafia ai foi inductance, e pei o le sili ona taatele o le tutusa savali i le laina, ina ia mafai ona tatou maua le aafiaga o le faʻaititia inductance, soʻoga inductance faateleina, ae o le downside o uaea ae faʻateleina foʻi le numera o capacitance, o lea i le mamanu o matagaluega laupapa, tatau ona tusa ai ma le tulaga faʻapitoa e filifili ai le sili ona talafeagai uaea.
3, e le gata ile faʻamatalaina muamua, faʻaosooso ma taʻitaʻiga a le laupapa femalagaaʻi ogatasi, o le crosstalk i le va o le manaʻoga e uaʻi atu i lenei vaega o loʻo i ai pea se uaea, e pei o le naʻo taʻua tutusa faʻataʻitaʻiga o le a taumafai e aloese mai le mamao mamao tutusa fesoʻotaʻiga, ma ona taumafai lea e tuʻu le va i le va o laina ma laina, faʻapea foʻi ma faʻailo uaea ma uaea eleele ma le paoa uaea le kolosi, Afai o loʻo i ai se uaea faailo sili ona maaleale, oe mafai ona faʻaopopo se taofiofi uaea e aloese ai crosstalk, lea e mafai foi ona lelei taofiofia crosstalk.
