Monochrome TV Transmitter - Block Diagram and its Workings: The term monochrome stands for black and white. Thus a monochrome TV system does not process variations of colour in a…
What is Optoelectronic Devices? Optoelectronics is the technology that combines optics and electronics and the devices based on this technology are known as optoelectronic devices. These devices include emitters, sensors…
Time Base Generator - Working Principle and Types: Time base is an axis, normally X-axis, that is used to represent time so that variations of quantities such as voltages, currents…
Uninterruptible Power Supply (UPS) - Block Diagram and its Workings: Uninterruptible Power Supply (UPS) - Most of us take the mains ac supply for granted and use it almost casually…
Switch Mode Power Supply (SMPS) or Switching Regulators: Switch Mode Power Supply (SMPS) - The regulated power supplies described earlier were basically linear voltage regulators. A linear voltage regulator possesses…
LM340 Series Voltage Regulator: This LM340 Series Voltage Regulator is typical of the three-terminal voltage regulators. The block diagram is shown in Fig. 43.27. The built-in reference voltage Vref drives…
Controlled Transistor Series Regulator or Negative Feedback Regulator: A controlled transistor series regulator is shown in Fig. 43.6. This Controlled Transistor Series Regulator circuit is quite similar to that of…
Regulated and Unregulated Power Supply: Almost all electronic devices used in electronic circuits need a dc source of power to operate. The source of dc power is used to establish…
