Gyroscopic Flight Instruments
Definition Gyroscopic Flight Instruments are instruments which have a mechanical gyroscope incorporated into their design. Description Gyroscopic flight instruments of some description are used in most general aviation aircraft and…
curvilinear translation
Curvilinear Translation (Projectile Motion) Projectile motion follows a parabolic trajectory. The vertical component of projectile is under constant gravitational acceleration and the horizontal component is at constant velocity. For easy…
Engineering Mechanics
INTRODUCTION Mechanics is the physical science concerned with the behaviour of bodies that are acted upon by forces. Statics is the study which deals with the condition of bodies in equilibrium subjected…
Direct sequence modulation
A collective class of signaling techniques are employed before transmitting a signal to provide a secure communication, known as the Spread Spectrum Modulation. The main advantage of spread spectrum communication technique…
Cellular concept
The immense potential of conventional telephone cannot be exploited to its maximum due to the limitation imposed by the connecting wires. But this restriction has been removed with the advent…
Wireless Communication
INTRODUCTION Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors. Wireless communication is a broad term…
Markovian processes
A stochastic process is called Markovian (after the Russian mathematician Andrey Andreyevich Markov) if at any time t the conditional probability of an arbitrary future event given the entire past of the process—i.e., given X(s) for all s ≤ t—equals the…
power density spectrum
(Sometimes called power spectrum.) A measure of the contribution to the total variance from a given frequency band in the generalized Fourier representation of a random function. If f(t) is a random function, the total energy is infinite,…
Bayes’ Theorem
Bayes' Theorem is a simple mathematical formula used for calculating conditional probabilities. It figures prominently in subjectivist or Bayesian approaches to epistemology, statistics, and inductive logic. Subjectivists, who maintain that rational belief is governed…
Discrete and Continuous Random Variables
A variable is a quantity whose value changes. A discrete variable is a variable whose value is obtained by counting. Examples: number of students present number of red marbles in a jar number…
