Mayelana nalolu hlelo lokusebenza
Lolu hlelo lokusebenza ngeke ukucacisa S / N for FM izwi lapho umsebenzisi engena Baseband nobuningi esiphezulu kanye bandwidth RF siteshi kHz, lo de-ukugcizelelwa in dB and owamukelayo C / N isilinganiso in dB. Ukubusa Carson isetshenziswa ukucacisa ukuphambuka peak imvamisa.
Njengoba isibonelo, faka Baseband imvamisa esiphezulu (BBF BW) = 3.4, RF channel bandwidth (RF BW) = 45, C / N = 13 kanye de-empasis P = 7, hit "Calculate" futhi Chile yakho kufanele ibe 48,0 dB .

Kubuyekezwe ngo-
Ukuphepha kuqala ngokuqonda ukuthi onjiniyela baqoqa futhi babelane kanjani ngedatha yakho. Ubumfihlo bedatha nezinqubo zokuphepha zingahluka kuye ngokusebenzisa kwakho, isifunda, nobudala. Unjiniyela unikeze lolu lwazi futhi angalubuyekeza ngokuhamba kwesikhathi.
Ayikho idatha eyabiwe nezinkampani zangaphandle
Funda kabanzi mayelana nendlela onjiniyela abaveza ngayo ukwabelana
Ayikho idatha eqoqiwe
Funda kabanzi mayelana nokuthi onjiniyela bakuveza kanjani ukuqoqwa
