Illustrate about the Digital televisions
Microprocessor would be used to control the below features, for instance:
- Automatically tuning into television stations
- allow digital signals to be decoded
- Since constantly monitoring signal strength (etc.) far better sound and picture quality result)
- allows interface with numerous devices
- In built diagnostics in case of faults
- Controls picture and sound quality (factory settings can be stored, etc.)
WHAT IS MIDPOINT BIASING OF A TRANSISTOR?
Active-mode NPN transistors in circuits Figure: Structure and use of NPN transistor. Arrow according to schematic. The figure opposite is a schematic presentation
Determine the shaft power output: A 6-pole, 50 Hz, 3-phase induction motor running on full load develops a useful torque of 180 Nm when the rotor emf frequency is 2 Hz. Determ
Explain Stator of a Synchronous Machine? The stator of a synchronous machine is made of thin laminations of highly permeable (silicon) steel in order to reduce the core losses.
Q. Regions of operation in BJT ? Transistor find many applications like amplifier, switch etc. depending upon the polarity and the magnitude of the applied voltages across the
Q. Principle of Three-phase synchronous machines? In fact, with very few exceptions, three-phase synchronous machines are most commonly used for power generation. In general, t
Explain Sampling at the Nyquist Rate? What would happen if we reduced the sampling frequency? In the time domain, we would be getting less samples for each period. In the frequ
The relationship between cell and batteries Generally, a cell delivers a certain voltage that is a function of what chemical reactions are taking place to generate the voltage
Faraday conducted a series of experiments on coils in a magnetic field. He found that if the magnetic flux density threading a coil were changed, a voltage was induced in the co
Q. DC Motor Characteristics? We gain an understanding of the speed-torque characteristics of a dc motor from Equations. In shunt motors, the field current can be simply control
