Platahoi analogi-raqami va raqami-analogi

Dar bisyor sohahoi tekhnika, tib, biologiya va gayra bazan lozim meoyad, ki az datchikhoi beruna signalho ba kompyuter dokhil va bad tahlil karda shuda, dar asosi in malumotho tajhizoti beruna idora karda shavand. Masalan, dar bemorkhonahoi zamonavi imkoniyati ba marizhoi duchori kasalihoi dil payvast namudani datchikho mavjud ast, ki onho kardiogrammai marizhoro muntazam ba kompyuter dokhil menamoyand. Dar mavridi khuruji kasalii bemor, kompyuter ba tavri avtomati, bo yorii yagon asbobi digar, tabibonro ogoh mekunad.

platahoi-analogiAgar dar garmkhona ba kompyuter datchikhoi chenkunandai harorati havo, namigari va tarkibi gazi havo payvast karda meshud, on goh dar asosi malumothoi hosilshudai kompyuteri dar garmkhona mikroklimati optimaliro tamin namudan mumkin bud.

Baroi dokhil va tahlil namudani signalhoi datchikho, boyad kompyuter bo platai makhsus mujahhaz gardonida shuda boshad, ki on signalhoi analogii az datchikho dastrasshudaro ba signalhoi raqamii kompyuteri tabdil dihad. CHunin platahoro tabdildihandahoi analogi-raqami meguyand. Baroi idorakunii asbobhoi beruna boshad, platahoi raqamianalogiro istifoda mebarand, ki onho baraks, informatsiyai raqamii kompyuteriro ba informatsiyai (signalhoi) analogii baroi asbobhoi beruna fahmo tabdil medihand.

Dar aksariyat mavridho dar kompyuterho funksiyahoi har du plataro yak plata ijro menamoyad.

Savolho:

  1. Modem va faks-modemho chi guna tajhizotand?
  2. Farqi strimer az vinchester dar chist?
  3. Vazifahoi multimedia az chi iborat ast?
  4. Boz kadom qismhoi ilovagii kompyuterro medoned?
  5. Platahoi analogi-raqami va raqami-analogi dar kujo va chi tavr tadbiq karda meshavand?

Suporish:

  1. Matni mavzuro bodiqqat khoned va onro naql kuned.
  2. Qismhoi ilovagii kompyuterro dar shakli tablitsa tasvir namoed va funksiyahoi onhoro nombar kuned.
  3. Agar dar sinfkhonai kompyuteri ba kompyuterho yagon qismi ilovagi payvast karda shuda boshad, on goh nomi onro gued va dar borai kharakteristikahoi on malumot dihed.
