Resistor Transistor Logic (RTL)
The resistor-transistor Logic(RTL) circuit is one of the basic logic circuits in digital logic families. It is a bipolar saturated device. The RTL logic is popular because of its simplicity….
Classification and Characteristics of Digital Logic Family
Digital logic family is a group of logic gates constructed using passive devices like a resistor, transistor, diodes, etc. Such devices have compatible logic levels and supply voltage with certain…
Hamming code with solved problems
Hamming code is used to detect and correct the error in the transmitted data. So, it is an error detection and correction code. It was originally invented by Richard W….
Error Detection and correction codes | Parity code
An error is the common cause of any system, either it may be digital or analog. Error detection and correction codes allow the detection and correction of an error while…
Basic Definitions in Magnetic circuit
The magnetic circuit is analogous to the electric circuit. A magnetic circuit has a closed path, through which magnetic flux will flow. There are several terms involved in the magnetic…
Armature reaction in DC Generator | Demagnetization and Cross magnetization
Armature reaction is the effect of magnetic flux produced by the armature current on the distribution of flux under the main poles of a DC generator. The armature flux produces…
Types of Armature winding | Drum winding – Lap winding – Wave winding
Armature winding is an arrangement of conductors in order to develop the desired emf by relative motion in the magnetic field. Based on the arrangement of conductors, there are several…
Armature winding | Pole Pitch – coil pitch – front pitch – back pitch
Armature winding is one of the most important parts of the DC Generator. In armature winding, you have to be clear with several terms like coil sides, coil pitch, pole…
Characteristics of self-excited DC Generator
For self-excited DC generator, the performance is analyzed with three different characteristics. They are no-load characteristics, internal and external characteristics. In this section, you will be learning about the characteristics…
