DC Potentiometer is an instrument which measures voltage, current and resistance. It can be used to calibrate ammeter and voltmeter.
-
Nyquist Stability Criterion gives the frequency response as well as comments on the stability and the relative stability of the system.
-
The Conventional Energy Sources are helpful in producing electrical power generation from Hydro, Thermal, Nuclear and Diesel power stations.
-
The Non-Conventional Energy Sources are those which are available for us at any time and are free of cost.
-
The 8255 microprocessor is also known as Programmable Peripheral Interface. It has 24 I/O pins. The three 8 bit ports are PA, PB, PC.
-
The DC Motor is an electrical machine which can be classified as Separately excited DC Motor, Permanent Magnet and Self excited DC Motor.
-
The DC Motor is an electrical machine which converts mechanical energy into electrical energy. It works on the principle of induced emf.
-
An interrupt is a condition that arises during the working of a microprocessor. The interrupts of 8086 initiate interrupt service through ISR
-
The circuit which produces the samples of the input voltage and holds those values for a definite amount of time is sample and hold circuit.
-
The precision rectifier has the capability of rectifying voltages which are of smaller magnitude than the forward voltage drop.
-
A Servo motor is similar to an induction motor having two primary windings placed 90 degrees apart in magnetic position.
-
The Nyquist criteria is a semi graphical method that determines stability of CL system investigating the properties of the frequency plot.
-
The state variables can be explained as a minimal set of states of a system which helps to determine behavior of the system.
-
The Routh Hurwitz’s Criterion states that the system is stable if and only if all the elements in the first column have same algebraic sign.
-
The Feedback amplifiers increase the signal strength by providing feedback back to the system at the input end.
-
The IMPATT diode (Impact ionization Avalanche Transit-Time) is one which is used in high frequency applications and is a high power diode.
-
Wien bridge oscillator is an audio frequency sine wave oscillator of high stability and simplicity with no phase shift in feedback network.
-
The Half wave rectifier uses a single diode and is the simplest form of diode. The connection allows the diode to conduct in only one cycle.
-
The Adaptive Delta Modulation technique helped to overcome the problem of granular noise in delta modulation.
-
There are three operational amplifiers in the circuit of an Instrumentation Amplifier of which two non inverting amplifiers are the inputs.
-
Crystal Oscillator is specially designed in a circuit to provide low impedance when it operates in series-resonant mode and high impedance.
-
CMOS is a new type of MOSFET logic is made combining both the PMOS and NMOS processes and is called complementary MOS.
-
The amplitude of the carrier signal varies in accordance with the instantaneous amplitude of the modulating signal in Amplitude Modulation.
-
Frequency Modulation is the technique in which the frequency of a carrier signal is varied according to the message signal.
-
As proposed by Hendrik W. Bode a Bode Plot is simply a graphical representation used to design and analyze any control system.
-
In PAM, amplitude of pulses is varied in accordance with the instantaneous value of modulating signal. It is basic technique for all modulation
-
The Delta Modulation has step size much smaller after quantization and also the sampling rate is much higher.
-
When a semiconductor is doped with half of the trivalent impurity and other half with pentavalent impurity is then called PN junction diode
