Learning is a gradual process, which can be expedited by experimentation.
Electronic experiments therefore constitute a fundamental part of an electronic
engineering student’s curriculum. Physical experimentation no doubt has its own
merits but it has the serious drawback of limiting the student’s practical knowledge
to the prescribed experiments. It takes away the opportunity of doing something that is so
characteristic of their age, exploration. To satisfy the students’ inherent
scientific curiosity what is required is a cost-effective system, which will allow them to
do 'just their own thing'. That is what makes the learning process complete, an
environment conducive to experimentation without the fear of destroying components or
devices. Not having to work with physical devices, the students can experiment till they
achieve desired results.
If one were to think about it,
Having to
pore over the box of resistors checking the different
color codes to get a particular value of resistance.
Twisting
and turning the knobs of the CRO for that one crucial
elusive position which will display the output waveform.
Not
getting an output for the final examination just because
one tiny transistor was faulty.
Wondering
what would happen to a particular circuit if a different
value of resistance or capacitance were used.
Something
goes wrong with the breadboard.
Compromise on circuit design
because there is no component in the college laboratory
that fulfils the requirements.
Spend
hours with the mulitimeter and CRO troubleshooting the
circuit
And the list just goes on.
"Circuit Simulation with EDWinXP" has been created in accordance
with the Syllabus followed by Technical Schools. Its main purpose is to illustrate the
study of circuit behavior using the EDWinXP CAD/CAE Package. Laboratory experiments
such as Amplifier, Filter, Multivibrator, Rectifier circuits etc have been demonstrated
and the results verified. Also included is Modelling which consist of extended user subroutines whereby a
user can create his own models to simulate the working of a particular
component.
