What is Group Technology (GT)?
Posted on April 17, 2011 by admin |
Group Technology also known as GT, is a manufacturing technology where similar parts are collectively identified and
grouped to use the benefit of their relationship in design and as well
Electrical Discharge Machining (EDM)
Sometimes it is referred to as spark machining, spark eroding, burning, die
sinking or wire erosion
Its a manufacturing process whereby a desired shape is obtained using
electrical discharges (sparks).
DIGITAL: LESSON 4
Combinational Logic Circuit
CLC consists of input, two or more basic logic gates and
A CLC performs an operation
Ways of representation numerical
Analog electronics involves
quantities with continuous values
Example: time, pressure,
Digital electronic involves
In the last classes:
Working of diode, V-I characteristics
When diode connected in series and
Zener diode as voltage regulator
Half wave rectifier
Why are transistor so important?
Much of the progress in the past 60 years has been because of the
success of the transistor.
Inverted in the 1940s, it repalced vacuum tubes in televisions,
radios and other electronic equipment.
The Zener Diode
* Zener diode is designed for operation in the reverse-breakdown region.
* The breakdown voltage is controlled by the doping level (-1.8 V to -200
* The major application of Zener diode is to prov

Digital Part: Lesson 3
Maurice Karnaugh introduced k-map in 1953 as a
next edition of Edward Veitchs (1952) Veitch
Used for minimizing
Rectifier with Filter
Rectifier output is not a pure d.c voltage ;
it contains fluctuations or ripples at the
output(ac harmonics). To remove these
ripples, filter circuits are used.
Filter is connected between rectifier and
Digital Part: Lesson 2
The variables that define the inputs and
outputs of logic circuits are called Boolean
There are only two values in Boolean Algebra.
So, its much easier to work with Boolean
What is a Broach?
A broach is a series of progressively taller
chisel points mounted on a single piece of
steel, typically used to enlarge a circular
hole into a larger noncircular shape such
as a square or other desired shape.
