SECTION-B
2. Explain the block diagram and architecture of VI. Why is it preferred over conventional
Instrumentation? Explain.
3. Create a VI that graphs the function sin (x), where x = 0??????.n ? and integral
y =
0
sin
n
xdx
?
?
. The value of n should be an input on the front panel.
4. What are local variables in LabVIEW? With the help of an example explain why they are
required?
5. What are the different functions required for the image acquisition? Build a VI that
acquires a image stored in a bit map file named soni.bmp. Convert that image into an
array and display the result.
6. Explain the software and hardware installations aspects required in virtual
instrumentation.

SECTION-C
7. a. Build a VI that functions like a calculator. The front panel should have digital
controls to input two numbers and a digital indicator to display the result of the
operation (Add, Subtract, Divide, or Multiply) that the VI performs on the two
numbers.
b. Build the block diagram and the front panel of a VI that act as an oscilloscope.
8. Explain the following (with the help of suitable VIs) :
a. Sequence structure and its need
b. WHILE and FOR loops
9. Discuss the following :
a. Windowing & Filtering
b. RS232
