Ingcaciso yeMveliso
1. IsiShwankathelo seMveliso
Isetyenziswe ngokufanelekileyo kwi-bi-directional transmission (inokugcinwa) kunye nokulinganisa ukulinganisa kwe-multi-class trunk transmission okanye inethiwekhi ephezulu efunekayo yokusabalalisa. Yamkela i-PHILIPS, iimodyuli eziphindwe kabini zamandla e-NEC. I-Audio pre-amplifier yityhubhu ye-microwave enengxolo ephantsi yokutyhala-tsala iamplifier ukuqinisekisa inzuzo eyaneleyo. I-1 igalelo kunye ne-2 iziphumo, kwaye uxhumano ngalunye lunokhuseleko lwangoku. Isebe lemveliso okanye ukuhanjiswa kunokutshintshwa ngokuyilandela. I-Double-equalizer isetyenzisiwe, ngoko ke ukulungelelanisa ukuhamba kweeklasi ezininzi kulula kwaye kulula. I-Attenuator kunye ne-equalizer zi-plug-in, ngoko abathengi banokukhetha isimbo esisisigxina okanye esinokulungiswa. Amandla okutshintsha athembeke kakhulu (okanye amandla angqamene) kunye noyilo olungqongqo lokungangeni kwamanzi kunye nokuchasana neendudumo luqinisekisa umsebenzi ozinzileyo.
