MT-43: The latest technologies: Color Television;

Task-1: Read the text and discuss it;
Text: Color Television
Color television is the transmission and reception of images in the full color. The color television system can produce programs both in color on color receivers and in black and white on monochrome receivers. Also, color receivers receive monochrome pictures when they are being transmitted.
Color transmission contains two basic components – brightness information and color information. Red, green and blue are the colors that are chosen for color television.
In a color camera an optical system separates the red, green, and blue image components of a picture and concentrates these three components in separate but identical color camera tubes.

Rangli televidenie tizimi rangli qabul qilishlarda ham, monoxrom qabul qilishlarda ham oq va oq rangda dasturlar ishlab chiqarishi mumkin.

Rangli qabul qilgichda kiruvchi signal chastota va amplitudali selektiv davrlardan o'tadi.

Bu sxemalarda yorqinlik komponenti rang komponenti va gorizontal va vertikal nurli sinxronlashtiruvchi komponentlar ajratilgan.

Yorqinlik komponenti bir vaqtning o'zida uchta elektron qurolga qo'llaniladi.
