BLOCKS TO MAKE A TV
Since the introduction of television formats they began to develop at the same time as technology evolved, color television appeared, many elements that made the old models were established in integrated circuits called jungle Y / C, and consist of microcontrollers. As a result the structure of television is made up of several stages:
BALUN AND TUNER. Mainly found the BALUN which is responsible for its proper impedance coupled with the tuner.
The tuner receives the signal provided by the antenna, the signal is called frequency and its output is obtained MF this in order to select only the channel signal selected by the user. BLOCK
FI. This stage is the one that receives the IF signal from the tuner and is responsible for rejecting the other signals outside. Slector
INPUT. Are the variety of inlets that are needed when the user wishes to choose deferens audio and video sources.
STAGE VIDEO. At this stage, separates the video signal from the audio signal, this signal is sent to the screen.
AUDIO STAGE. As in the previous stage is separated from the audio video, this audio signal is sent to the speaker but you must be filtered, amplified volume control. SEPARATOR
Y / C. This stage is where separates the chroma and luminance signal and found in a same bandwidth as this is done through the video signal and no audio. PROCESS
Y. to transmit the signal of black and white screen you need to apply a series of processes, as a small delay, control of brightness and contract, amplification, etc. C. PROCESS
To send the signal to the display color is a more complicated process than in the Y signal, because we first need to retrieve the color burst and then synchronize it with the oscillator, then demodulated in phase and amplitude, thus obtaining the 3 color signals red, green and blue. MOTHERBOARD
kinescope. This is where the processes are combined.
kinescope. This is used in television monitors, is the most important since it is responsible for converting the electrical signal into an image.
SYNCHRONY. In the video signal requires a series of horizontal sync pulses and vertical image is displayed correctly.
YOKE. Is charged to sweep the electron beam to build the image, this is constituted by a horizontal deflection coil and vertically without the yoke would not only be the beam in the center and observe the display white point .
SYSCON. Is a control system and one of the most important, as its name suggests is responsible for monitoring all aspects of operation receptor, such as turning on and off, volume, remote, channel tuning. For this reason it is considered the brains of the TV. POWER SUPPLY
. Every element must be fed by an external source, such is the case of television that many would think that this source can be anything in our homes receive the AC power but this is not appropriate for this reason independent sources are used, a responsible for feeding the common circuit television and one that feeds the control system.
