Tambayoyi
Tambaya: Me yasa Ba a sami Abubuwan Shiga ba?
A: Abubuwan shigar da madaidaici su ne waɗanda ke kawar da shigarwar da ba a zaɓa ba sannan su aika zuwa wani shigarwar. Wannan yana ba ku damar sarkar daisy abubuwan shigarwa kuma ku ƙare kawai a shigarwar ƙarshe. Wannan yana aiki da kyau don bidiyo mai ƙarancin mita kamar NTSC (composite) a 5MHz, amma ba don HDTV mai girma ba inda mitoci zasu iya kaiwa sama da 37 MHz. Dole ne a dakatar da shigarwar don hana tunani akan kebul da kula da bandwidth.
Tambaya: Zan iya raba Analog Audio da wannan DA?
A: Ee, amma matakin (Volume) na iya saukewa daga 2dB zuwa 30dB saboda ƙarancin shigar da ƙara (75 ohms). Wasu kayan aikin mai jiwuwa tare da ƙarancin ƙarancin fitarwa na iya ciyar da wannan DA tare da sakamako mai karɓuwa, amma yawancin za su sami babban rauni wanda zai haifar da asarar sigina mara yarda.
Tambaya: Zan iya raba Digital Audio (SPDIF)?
A: Ee. SPDIF kawai AES/EBU audio dijital ne wanda aka tsara don gudu akan kebul na Coax kamar bidiyo.
Tambaya: Har yaushe na USB na bidiyo zai iya zama?
A: The ampliifiers a kan abubuwan da ake fitarwa na iya fitar da igiyoyin bidiyo masu kyau fiye da mita 100 (328ft). Shawara mafi kyau ita ce kiyaye igiyoyi zuwa shigarwar a tsawon madaidaicin tsayi, ƙasa da mita 5 (fiti 16), sannan a haɗa kamar yadda ake buƙata akan fitarwa.
Tambaya: Menene bandwidth ake buƙata don HDTV?
A: Yawancin HDTVs suna da bandwidth na 37MHz. Kuna son duk wuraren sauyawa da wuraren rarraba ku su sami damar sarrafa aƙalla ninka wannan mitar. Makullin don tunawa shine ƙayyadaddun 3dB. Wannan yana wakiltar mitar da siginar asali ta kasance a 70% ko asarar 30%.
