VISION

To see a vision
when going for a mission
in the era of multi-faceted fission

Let's understand the fugitives 
of this broken mind
which hinders it's success
tries so many times to bind


The real vision is awaited
till the mission stands completed

Quotation by Eric Hoffer



The difficult and risky task of meeting and mastering the new—whether it be the settlement of new lands or the initiation of new ways of life—is not undertaken by the vanguard of society but by its rear. It is the misfits, failures, fugitives, outcasts and their like who are among the first to grapple with the new.

Eric Hoffer (1902–1983), U.S. philosopher. The Passionate State of Mind, aphorism 51 (1955).

A Quotation

When you are about to badger the weak,
Then imagine yourself before a more powerful man.

Tiruvalluvar (c. 5th century A.D.), Tamil sage, poet. repr. Calcutta, Y.M.C.A. Publishing House (1958). The Sacred Kural, translated from the Tirukkural of Tiruvalluvar by H.A. Popley, vs. XXV.10 (1931).

Legends say that the author was either a Jain monk or a Hindu outcaste priest.

Electronics Concepts

1. When a transmission line or waveguide is mismatched by a load, a standing wave is created in the line or the waveguide. The distance between two adjacent maxima or minima is one half of a wavelength.


2. The radius of Earth is 6378 KM.

3. Charge on one electron is 1.6 * 10 (pow -19) coulomb

4. Minimum 3 identical RC high-pass sections connected in cascade are required in a phase-shift oscillator.


5. In a microwave circuit with waveguides, a waveguide twist is used for rotating plane of polarization.

6. Microstrip line has the combined characteristics of dielectric, ohmic and radiation losses.


7. A duplexer uses same antenna for reception or transmission without interference.


8. X-band frequencies are in the range of 8.0 to 12.0 GHz.

9. The advantages of cycle stealing in DMA are:
  
      a. It increases the maximum I/O transfer rate.
      b. It reduces the interference by the DMA controllers in CPU's memory access.
      c. It is beneficially employed for I/O devices with shorter bursts of data transfer.



10. An FM radio station performs better than an AM station radiating the same total power as FM is immune to noise.

Electronic Facts

1. Electrons in a pair spin in opposite directions, their opposite spins cause their magnetic fields to cancel each other.

2. Quartz Crystal: A slice of quartz grounded to a prescribed thickness that vibrates at a steady frequency when stimulated by electricity. The tiny crystal about 1/20th by 1/5th of an inch, creates the computer's heartbeat. It is piezoelectric, generate electricity when subjected to pressure.
Resistor symbol

Capacitor symbol3. Resistors are used to lower the level of current in a closed loop.





4. Capacitors are electronic components used for storing small amount of electricity. That explains how radios keep playing for a couple of seconds even after unplugging them.

5. Amplifiers are used to make weak signals stronger.Amplitude modulated signal stays on one exact frequency.

6. Frequency modulated signal is transmitted by changing its frequency.FM radio waves always stay on the same amplitude.

7. The electricity running through human's brain is of too small a magnitude to be measured by most electrical equipments.

8. To generate a  radio wave, electric field must be continuously changing.

9. Electronics is a branch of physics that deals with how electrons behave in vacuum or gases.Electricity is the group name of  energy possessed by energized electrons.

10. Electronic systems normally use relatively small amounts of  electric energy to process or transmit information.

11. Homes usually have AC supply.Electronic components have a transformer to convert AC to DC.

Electronic Terms

Boltzmann Constant:

In joules equals  1.3806503 × 10-23 (m2 kg s-2 K-1  ) or joules per kelvin


In electronvolts, the Boltzmann constant is 8.617 343(15) × 10−5 eV/K


Symbol: 
Used to define the relation between absolute temperature and the kinetic energy contained in each molecule of an ideal gas, a constant of proportionality for temperature and energy
http://en.wikipedia.org/wiki/Boltzmann_constant




Avogadro's Number:

The number of atoms needed such that the number of grams of a substance equals the atomic mass of the substance,

An Avogadro's number of substance is called a mole. For example, a mole of carbon-12 atoms is 12 grams, a mole of hydrogen atoms is 1 gram, a mole of hydrogen molecules is 2 grams, etc.

Faraday's constant:
It is the charge carried by one mole of electrons. There are 6.02214e23 electrons per mole of electrons. (Avogadro's number)
Each electron has a charge of 1.602177e-19 coulombs per electron.
So Faraday's constant is 1.602177e-19 coulombs per electron * 6.02214e23 electrons per mole of electrons = 9.64853e4 coulombs / mole of electrons.
This constant is useful to us when we are doing problems in electrolysis.
