switches off/on an LED. IC 741 Integrator circuit/Comparator circuit.
To operate a small loud speaker by generating oscillations
using IC 555.
Question paper pattern:
Examination will be conducted for 100 marks with question
paper containing 10 full questions, each of 20 marks.
Each full question can have a maximum of4 sub questions.
There will be 2 full questions from each module covering
all the topics of the module.
Students will have to answer 5 full questions, selecting
one full question from each module.
The total marks will be proportionally reduced to 60 marks
as SEE marks is 60.
