Are you curious and willing to know what you will learn from your electrical engineering degree? You have definitely come to the right place.
It is a DC motor which rotates in steps. After the electrical signal is fed to the motor, it starts to rotate in steps. The speed of the motor is dependent on the rate of input signal applied. The input applied to the motor decides the direction of rotation of the motor. The rotor is a permanent magnet which rotates.
Transducer is a device which converts physical quantity or energy of one form to signal or energy of another form.
The basic working of an induction motor is producing a rotating magnetic field and this field is sinusoidally distributed.
The Polar Satellite Launch Vehicle is known as PSLV. This technology is the most challenging space program for the Indian space program till now.
The Switched mode power supply is abbreviated as SMPS is used to convert the regulated DC output voltage from unregulated DC or AC voltage.
The Digital to Analog converter is an electronic device which converts digital signal to analog signal. Weighted Resistor and R-2R Ladder are its types.
The microprocessor 8086 minimum mode and maximum mode operation is decided by signal MN/MX’. When the signal MN/MX’ = 1 the 8086 minimum mode is active.
TDMA (Time division multiple access) is used where there is no need for continuous transmission. Due to this it can be used instead of FDMA.
Whenever a signal is sampled below Nyquist rate (fs < 2B), the signal is called under sampled and the Aliasing effect hampers the results.
The multiplexer is a special type of combinational circuit which has n-data inputs, one output and m inputs select lines with 2^m = n.
The Feedback amplifiers increase the signal strength by providing feedback back to the system at the input end.
Snubber Circuit is the one used for suppressing voltage spikes. These are energy absorbing circuits. RC circuits are basic snubber circuits.
The clipper circuits are basically used to clip the portion of any input signal without changing the remaining part of the input waveform.
A controller which controls the motor is called Variable Frequency Drive. By varying the frequency and voltage of supply it controls the motor
