What does horizontal deflection mean?

What does horizontal deflection mean?

The category descriptions and the measures they include are presented below. A horizontal deflection hinders the ability of a motorist to drive in a straight line by creating a horizontal shift in the roadway.

What is horizontal deflection circuit?

A horizontal deflection circuit for a television receiver including a deflection unit, means for controlling sweep, means for controlling commutation and means for controlling the energy applied to the horizontal final stage.

What is the use of horizontal deflection?

These plates are thus referred to as the horizontal and vertical deflection plates. The combination of these two deflections allows the beam to reach any portion of the fluorescent screen. Wherever the electron beam hits the screen, the phosphor is excited and light is emitted from that point.

What is horizontal circuit?

A horizontal deflection circuit makes a sawtooth current flow through a deflection coil. The current will have equal amounts of positive and negative current. The horizontal switch transistor conducts for the right hand side of the picture. The damper diode conducts for the left side of the picture.

What is a horizontal oscillator?

The oscillator that produces, under control of the horizontal synchronizing signals, the sawtooth voltage waveform that is amplified to feed the horizontal deflection coils on the picture tube of a television receiver. Also known as horizontal oscillator.

How is vertical deflection calculated?

Generally, deflection can be calculated by taking the double integral of the Bending Moment Equation, M(x) divided by EI (Young’s Modulus x Moment of Inertia).

What is the function of horizontal deflection circuits in television?

As in the vertical system; there is generally a driver between the Television Horizontal Deflection Circuit oscillator and the horizontal output stage. Its function is to isolate the oscillator and to provide drive power for the horizontal amplifier.

What is horizontal output transistor?

The horizontal output transistor (HOT) is a switch. It provides a path for current to flow through the flyback’s primary winding and horizontal yoke as shown in Figure 2. The HOT is switched on and off by a signal applied to the base. This drive current is supplied by the horizontal driver and driver transformer.

What is CRO and CRT?

The CRO recruits the cathode ray tube and acts as a heat of the oscilloscope. In an oscilloscope, the CRT produces the electron beam which is accelerated to a high velocity and brings to the focal point on a fluorescent screen. Thus, the screen produces a visible spot where the electron beam strikes with it.

What is vertical deflection system?

The function of vertical deflection system is to provide an amplified signal of the proper level to drive the vertical deflection plates without introducing any appreciable distortion into the system.

What is horizontal deflection yoke?

A deflection yoke is a kind of magnetic lens, used in cathode ray tubes to scan the electron beam both vertically and horizontally over the whole screen. In a CRT television, the electron beam is moved in a raster scan on the screen. Electromagnetic deflection yokes are also used in certain radar displays.

What is a deflection circuit?

[di′flek·shən ‚sər·kət] (electronics) A circuit which controls the deflection of an electron beam in a cathode-ray tube.
