The Molecular orbital theory was utilised initially to emphasize the bonding in molecules as the valence band theory could not explain the bonding in molecules.

Calcination is a very simple chemical process, where the solid material or the substance is heated in a controlled environment, in the process the temperature is also regulated

A function f(x) is said to be periodic function if f(x + T) = f(x) for all real x and some positive number T.

If u and v are functions of the two independent variables x and y , then the determinant, is known as the jacobian of u and v with respect to x and y.

A function is said to be analytic function at a point z0 if f is differentiable not only at z0 but an every point of some neighborhoods at z0.

If we get a square matrix from an identity or unit matrix by using any single elementary transformation is called elementary matrix.There are two types of echelon form of a matrix.

The t-distribution, which is also known as the student’s t-distribution, is the continuous probability distribution. It looks like a normal distribution.

Bravais lattice gives information of the periodic array in which the repeated units of the crystal are arranged.

Shock waves are strong pressure waves in any elastic medium like water, solid or air. Supersonic aircraft or lightning produce Shock waves.

Helium-Neon Laser laser is a gas laser. In this a mixture of helium and neon gas is used as a gain medium. It was the first continuous-wave laser.

CRO or Cathode Ray Oscilloscope displays and measures the electrical signals, time intervals and phase shift between two electrical signals.

Overview (sequence and series) A function f : N  , where S is a non-empty set , is called sequence , for…

Pumping is the process to achieve population inversion .

Watchdog timer is a hardware microcontroller. It is basically used to take out a system from an infinite loop and resets the system.

The regula-falsi method is the oldest method of finding the approximate numerical value of a real root of an equation f(x) = 0.

this type of isomerism occurs by arrangements of atoms or the functional groups that belong to atoms that are not similar in nature.

In 1960, Maiman constructed the Ruby laser. It is a three-level solid-state laser and is emitting red light of wavelength 694.3 nm.

Rate of Stimulated emission depends upon the number of atoms present in the excited state as well as the energy density of photons.

The number of atoms present in the excited state is greater than the number of atoms in the ground state is called population inversion.

Simple Harmonic Motion (SHM) is when the restoring force is directly proportional to the displacement of the body from its mean position.

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 IC 555 timer is an 8 pin chip. It is used in applications such as multivibratiors. It operates in astable, bistable and monostable mode.

The losses in transformer are listed below. Some of them occur due to alternating flux or due to ohmic resistance in the windings.

The Programmable Interrupt controller is also known as PIC micro-controller. It is used as interfacing device. It has different operating modes.

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.

FDMA allows users to transmit signals simultaneously to satellite transponders with the help of specific frequency to every user in a channel

In JK flip flop when both J=K=1 the output toggles as long as clock high. This makes the output unstable. This is called race around condition.

The convolution theorem states that the transform of convolution of f1(t) and f2(t) is the product of individual transforms F1(s) and F2(s).

Magnetic Hysteresis Curve represents the relation between magnetizing force (H) and magnetic flux intensity for ferromagnetic material.

Development plan is also known as a master plan. Development defined as the carrying out of building, engineering, mining or other operations.
