Multi core processor
Multi core processor is an IC (integrated circuit) in which two or more processors core have been packaged for superior performance, reduced power consumption, and more efficient simultaneous processing of multiple tasks. Multi core processor is a
Difference between TDM and FDM
Following are the difference between time division multiplexing and frequency division multiplexing. TDM FDM TDM stands for time division multiplexing. FDM stands for frequency division multiplexing. TDM is preferred for the digital signals. FDM is preferred for digital signals.
Difference between volt ohm milliammeter (VOM) and vacuum tube voltmeter (VTVM)
Following are the difference between volt ohm milliammeter (VOM) and vacuum tube voltmeter (VTVM) : Volt ohm milliammeter (VOM) Vacuum tube voltmeter (VTVM) In volt ohm milliammeter, DC voltmeter resistance changes with range. It is the same
Characteristics and applications of common base transistor amplifier
Characteristics: There are some characteristics of common base transistor amplifier which are given below, It has very high output resistance. It has low input resistance. Its voltage gain is of the order of 1500. Its current gain
What is modulation?
Modulation can be defined as the method of combining an audio frequency signal with a radio frequency carrier wave. The audio frequency is also known as modulating wave and the resultant wave produced is called as modulated
What is a ferromagnetic material?
The ferromagnetic materials are the most important magnetic materials used in electricity and electronics. They are easily and strongly magnetized in the same direction as the field. They have high value of relative permeability from 50 to
Factors affecting the frequency stability of an oscillator
The ability of an oscillator to maintain a constant frequency of oscillation is called as frequency stability. There are following factors affect the frequency stability which are given below, Operating point of the active device: The Q-point
Working principle of transformer
Electrical power transformer is a static device which transforms electrical energy from one circuit to another without any direct electrical connection and with the help of mutual induction between two windings. It transforms power from one circuit
What is the difference between power transformers and distribution transformers?
Power Transformers Distribution Transformers Power transformer transfers electrical energy in any parts of electrical circuit between generator and primary distribution circuit. Distribution transformer is a transformer for transferring electrical energy from a primary distribution circuit to a
Transformation of transformer technology
In the present era of civilization, thinking to live without electricity has almost become un-imaginable for most of the population all over the world as we make use of electricity in most of our daily living applications.
