RIP II Kolokvijum

The resolution of a screen is determined by multiplying the number of pixels horizontally and vertically. This means that the more pixels there are in both directions, the higher the resolution will be. The answer "proizvod broja piksela po horizontali i vertikali" (product of the number of pixels horizontally and vertically) accurately describes how the screen resolution is calculated.

The primary (active) colors used in monitors are red, green, and blue. These colors are combined in different intensities to create a wide range of colors on the screen. This is known as the RGB color model, where each pixel on the screen is made up of varying amounts of red, green, and blue light. By adjusting the intensity of each color, a monitor can display millions of different shades and hues.

The correct answer is "usmeravanje elektronskog mlaza na zeljenu tacku ekrana." The role of deflection coils (kalems, HSK, VSK) is to control and direct the electron beam to the desired point on the screen. These coils generate a magnetic field that interacts with the electron beam, causing it to move horizontally and vertically across the screen, creating the images we see.

The correct answer is the vertical stage. This is because a horizontal white line appearing on a CRT monitor indicates a problem with the vertical deflection circuitry. The vertical stage is responsible for controlling the movement of the electron beam vertically on the screen. If there is a fault in this stage, it can cause a horizontal line to appear on the display.

The correct answer is "broj ekrana koji se 'iscrtaju' u 1 sekundi" which translates to "the number of screens that are 'drawn' in 1 second." This refers to the frequency of vertical scanning, indicating how many times the screen is refreshed or updated per second.

The correct answer is "podaci za dva piksela i kontrolni signal" which translates to "data for two pixels and a control signal" in English. This means that the output of a scalar TFT monitor includes data for two pixels as well as a control signal. This suggests that the monitor is capable of displaying information for two pixels simultaneously, and the control signal is necessary for coordinating and controlling the display of these pixels.

The correct answer is "Impulsnog tipa" because an impulse signal is used to stabilize the voltage in the base of the transistor. An impulse signal is a short burst of energy that can quickly change the state of a circuit. In this case, it is used to regulate and stabilize the voltage in the base of the transistor, ensuring proper transistor operation.
