provided.
Spectrometer Setup is useful for understanding the behaviour of light
and it concerns with the phenomenon of Reflection, Refraction,
Diffraction and Interference of light. Optical spectrums are important
for the detailed description of light source and wavelength
determination for each colour of light. Spectrometer is basically an
instrument for observing spectrums and measuring angle of deviation of
light in a particular medium, for mathematical calculations. The setup
comprises of spectrometer, prisms, grating and light source, which are
necessary for all the experiments of spectrometer.

Error Detection and Correction-Cyclic Code Trainer - friendly learning platforms to provide a modern, portable, comprehensive
and practical way to learn Technology. Each TechBook is provided with
detailed Multimedia learning material which covers basic theory, step by
step procedure to conduct the experiment and other useful information.
Error Detection and Correction - Cyclic Code Scientech 2120 is designed
to provide the conceptual knowledge of code correction and detection by
adding the redundant bits to actual bit pattern, which are use to
represent the code word. Error detection is the ability to detect the
presence of errors caused by noise or other impairments during
transmission from the transmitter to the receiver. Error correction is
the additional ability to reconstruct the original, error-free data. A
Cyclic Redundancy Check (CRC) is a type of function that takes as input a
data stream of any length, and produces as output a value of a certain
space, commonly a 32-bit integer. The term CRC denotes either the
function or the function`s output. A CRC can be used as a checksum to
detect accidental alteration of data during transmission or storage.
CRCs are popular because they are simple to implement in binary
hardware, are easy to analyze mathematically, and are particularly good
at detecting common errors caused by noise in transmission channels. The
selection of generator polynomial is the most important part of
implementing the CRC algorithm. The polynomial must be chosen to
maximize the error detecting capabilities while minimizing overall
collision probabilities. The most important attribute of the polynomial
is its length i.e. the number of the highest nonzero coefficient,
because of its direct influence of the length of the computed checksum

BJT Ampilfiers and Emitter Follower Trainer - BJT Amplifiers and Emitter Follower Trainer -BJT Amplifiers and Emitter
follower Trainer Nvis 6542 is a unique product designed to explain the
role of BJTs as single-stage/multistage RCcoupled amplifiers and as
common collector emitter followers. One of the common method for
coupling two stages of an amplifier is RC-coupling. RC-coupled
amplifiers have the advantage of wide frequency response and relatively
small cost and size. Darlington transistors are circuits that combine
two bipolar transistors in a single device such that high current gain
(b) is obtained and lesser space is required than that used by two
discrete transistors. Nvis 6542 is useful for students in plotting the
frequency vs. gain response of BJTs and in the measurement of parameters
such as Bandwidth, Input Impedance etc.

Single Plate Diaphragm Spring Clutch Trainer, technical teaching equipment for engineering
The diaphragm spring (Fig. 24.5A) is a steel disc having a hole at the
centre, and the inner portion of the disc is radially slotted so that a
number of actuating (release-lever) fingers are formed. The outer ends
of the slots are provided with enlarged blunting holes, which distribute
the concentrated stresses created during deflection of the fingers, and
also provide a means of locating the shouldered rivets, which restrain
the fulcrum rings.
The diaphragm spring is placed between the pressure-plate and the cover
pressing (Figs. 24.6A and B). The outer edge of the dished spring bears
against the pressure-plate, and two round-sectioned wire rings are
positioned from a short distance from its outer edge, one on each side
of the dished spring. These two rings are located as well as held in
position by shouldered rivets and these rivets in turn are supported by
the cover pressing (Fig. 24.7).
During fastening of the cover-pressing to the flywheel, the dished
spring is slightly flattened, which loads the pressure-plate against the
driven friction discs, the spring reaction being taken
through the outer ring to the cover-pressing. The inner ring acts as a
pivot point for all the individual release-lever fingers and are located
near the periphery of the diaphragm spring to increase the leverage.....
