Amplification in Transistor: Current Amplification in Transistor - We already know that a transistor can be used for current amplification. A small change in the base current (ΔIB) produces a large…
Ward Leonard Method of Speed Control: Known after the name of its inventor Ward Leonard Method of Speed Control (1891), it consists of a separately excited generator feeding the dc…
Fiber Optic Components and Systems: The Fiber Optic Components and Systems can be divided into subgroups, the source, the link, and the detectors. We will now explore the makeup and…
Television System Articles: Introduction to Television: Introduction to Television tells first thing of seeing at a distance. To be successful, a television system may be required to reproduce faithfully: The…
Color Television Receiver Block Diagram: Figure 17-25 shows the block diagram of a Color Television Receiver Block Diagram, but for simplicity the circuits shown in Figure 17-23 are omitted. Interconnection…
Color Picture Tube Working: A Color Picture Tube Working requires correct sweep currents, input voltages and drive voltages. Having said this very quickly, it is now a good idea to…
Television Horizontal Deflection Circuit: The function performed by these circuits is exactly the same as already described for the vertical deflection circuits. There are some practical differences. The major one…
Vertical Deflection Circuit in TV: The Vertical Deflection Circuit in TV include the vertical oscillator and amplifier for vertical scanning at 60 Hz and a similar horizontal arrangement for scanning…
