Voltage Series Negative Feedback Amplifier: In a negative feedback amplifier, a small portion of the output voltage is fed back to the input. When the feedback voltage is applied in…
Interlocking Components in Electrical Drives: Sensing of signals required for speed and current control loops. Sequencing and interlocking operations are explained in the previous section, whereas this section discusses components…
Electrical Drive Systems: Each Electrical Drive Systems is different from other Electrical Drive Systems. However, there are some common features associated with all Electrical Drive Systems. To understand them it…
Semiconductor Converter Controlled Drives: These are now widely used both in ac and dc tractions involving dc and ac motors, and the conventional drives have all become outdated, and will…
Electric Traction Services: Electric Traction Services can be broadly classified as: Electric Trains. Electric buses, trams (or tramways) and trolleys. Battery driven and solar powered vehicles. Electric Trains: Electric trains…
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…
Color TV Transmission: Having discussed the manner of indicating luminance and the two components of chrominance in Color TV Transmission, it is now necessary to investigate how they may be,…
Monochrome Television Transmitter: As shown in the block diagram of Figure 17-2, a Monochrome Television Transmitter system is quite unlike any of the transmission systems studied previously. This section will…
